    Breast cancer screening is known to reduce breast cancer mortality. A high breast density may affect this reduction. We assessed the effect of screening on breast cancer mortality in women with dense and fatty breasts separately. Analyses were performed within the Nijmegen (Dutch) screening programme (1975-2008), which invites women (aged 50-74 years) biennially. Performance measures were determined. Furthermore, a case-control study was performed for women having dense and women having fatty breasts. Breast density was assessed visually with a dichotomized Wolfe scale. Breast density data were available for cases. The prevalence of dense breasts among controls was estimated with age-specific rates from the general population. Sensitivity analyses were performed on these estimates. Screening performance was better in the fatty than in the dense group (sensitivity 75.7% vs 57.8%). The mortality reduction appeared to be smaller for women with dense breasts, with an odds ratio (OR) of 0.87 (95% CI 0.52-1.45) in the dense and 0.59 (95% CI 0.44-0.79) in the fatty group. We can conclude that high density results in lower screening performance and appears to be associated with a smaller mortality reduction. Breast density is thus a likely candidate for risk-stratified screening. More research is needed on the association between density and screening harms. © 2016 UICC.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    Full Text Available Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer.DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively.Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    In March, 2010, the French Health Products Safety Agency suspended the sale of prefilled silicone breast implants manufactured by Poly Implants Prosthèse Prothese (PIP) because of a high failure rate and the use of an inappropriate silicone gel that did not comply with CE marking. These findings led to an international medical crisis. In France, 30,000 female patients had PIP implants. In our Department, 1150 PIP breast implants had been implanted in 630 patients since 2001. A retrospective study was conducted to define the rupture rate of these implants and the complications that arise. The women included in the study underwent implant removal from May 2010 to September 2012 for preventive or curative reasons. Data were collected from medical records that included: results of clinical examination, breast ultrasound before removal, rates of implant rupture, results of biopsy of periprosthetic capsule and pericapsule tissue and postoperative complications. A total of 828 PIP breast implants were removed in 455 patients. The rate of ruptured implants was 7.73% (64/828), corresponding to 11.6% of patients. A periprosthetic effusion was associated with rupture in 44% of cases. Breast ultrasound indicated a rupture for 87 implants; 32% were true positives and 3% were false negatives. Periprosthetic capsule biopsy demonstrated the presence of a foreign body, which seemed to be silicone, in 26% of cases and the presence of inflammation in 13% of cases. No siliconoma-type lesion was identified in the pericapsular tissue at biopsy. A total of 14 implants presented perspiration at removal. A statistically significant difference was found between the rates of rupture for texturised implants as compared to the smooth-surfaced implants. There were eight post-revisional-surgery complications (1%) and three cases of breast adenocarcinoma. The preventive explantation of PIP breast implants is justified given the high failure rate (7.73%) and given patients' exposure to silicone

    To determine the role of FNAC with histological confirmation in the diagnosis of tuberculous mastitis, and to highlights its importance by determination of frequency, clinical history, clinical presentation and laboratory investigations in our setup. The data was collected from patients 'files and other record, and the results tabulated. All were married multiparous women, aged 18-42 years, belonging to poor socio-economical class. One was pregnant, while three were lactating mothers. Associated pulmonary tuberculosis was present in three cases. Previous history of tuberculosis was present in one case, though five patients had a family history of tuberculosis. Lump in the breast, with or without ulceration/ abscess/discharging sinus was the clinical presentation of all the cases, as was low grade fever and pain. All patients had anemia and weight loss, though axillary lymphadenopathy was seen in five cases. ESR was raised in all the cases and the Mantoux test was positive. The glutaraldehyde test was positive, though it was performed in three cases only. AFB were seen in one case only. The diagnosis was made on FNAC by the presence of chronic granulomatous inflammation having caseating epithelioid granulomas and Langhan type of giant cells. The cytological diagnosis was confirmed by histopathological findings of excisional biopsy specimen in all the cases. The present study highlights the importance of tuberculous mastitis; its frequency being 2.3% in breast diseases. FNAC is an important initial diagnostic tool in patients having tuberculous mastitis, specially in the rural areas. It is safe, rapid, simple, cost effective and accurate, the accuracy being 100%.

    Objective: To improve the early diagnosis of breast cancer through a study of the mammography and CT findings of small breast cancer. Methods: The mammography and CT findings of 18 cases of small breast cancer (φ≤2.0 cm in diameter) were studied and compared with pathological results. Results: The diagnostic accuracy of CT and mammography was 83% and 61%, respectively. There was a statistical difference between both modalities (P<0.05), CT scan was superior to mammography. However, there was no difference between them when assessing the lesion arising in F-type breast. In detecting breast fine cluster of calcification, the sensitivity of mammography was better than CT scan. Conclusion: The patient suspected of small breast cancer should take mammography as the first evaluation. CT scan is reserved for the further investigation. The mammography combined with CT scan can improve the early diagnostic rate of breast cancer

    Growing evidence suggests that quantitative descriptors of the parenchymal texture patterns hold a valuable role in assessing an individual woman's risk for breast cancer. In this work, we assess the hypothesis that breast cancer risk factors are not uniformly expressed in the breast parenchymal tissue and, therefore, breast-anatomy-weighted parenchymal texture descriptors, where different breasts ROIs have non uniform contributions, may enhance breast cancer risk assessment. To this end, we introduce an automated breast-anatomy-driven methodology which generates a breast atlas, which is then used to produce a weight map that reinforces the contributions of the central and upper-outer breast areas. We incorporate this methodology to our previously validated lattice-based strategy for parenchymal texture analysis. In the framework of a pilot case-control study, including digital mammograms from 424 women, our proposed breast-anatomy-weighted texture descriptors are optimized and evaluated against non weighted texture features, using regression analysis with leave-one-out cross validation. The classification performance is assessed in terms of the area under the curve (AUC) of the receiver operating characteristic. The collective discriminatory capacity of the weighted texture features was maximized (AUC=0.87) when the central breast area was considered more important than the upperouter area, with significant performance improvement (DeLong's test, p-valuewomen's cancer risk evaluation.

    To find the association of various risk factors with breast cancer. Study Design: It was a case-control study. Place and Duration of Study: The study was carried out in NORI Hospital Islamabad and Combined Military Hospital Rawalpindi between August, 2013 and February, 2014. Material and Methods: Two hundred breast cancer patients and 200 control subjects were inducted. A short approved and planned questionnaire was used to collect data regarding basic demographic, menstrual and reproductive characteristics of participating females. Cases and controls were then interviewed after taking written consent. Results: Breast cancer patients and control subjects did not differ regarding age (p = 0.15), early menarche (OR for menarche at <13 years vs. ?13=1.3, 95% CI = 0.84 - 2.02), and history of breast cancer in 1st degree relatives did not increase breast cancer risk (OR = 1.0, 95% CI = 0.57 - 1.74). Nulliparous women had significantly higher risk than parous women (OR = 2.43, 95% CI = 1.22 - 4.84) and women with late menopause compared to women with early onset of menopause were also at higher risk for breast cancer (OR for menopause at ? 50 vs. < 50 = 5.16, 95% CI = 2.59 - 10.29). Conclusion: Nulliparity and menopausal age of more than 50 years was associated with increased breast cancer risk. Breast feeding and age less than 25 years at first live birth was not protective against breast cancer. (author)

    Molecular breast imaging (MBI) is a functional test used for supplemental screening of women with mammographically dense breasts. Additionally, MBI depicts variable levels of background parenchymal uptake (BPU) within nonmalignant, dense fibroglandular tissue. We investigated whether BPU is a risk factor for breast cancer. We conducted a retrospective case-control study of 3027 eligible women who had undergone MBI between February 2004 and February 2014. Sixty-two incident breast cancer cases were identified. A total of 179 controls were matched on age, menopausal status, and MBI year. Two radiologists blinded to case status independently assessed BPU as one of four categories: photopenic, minimal to mild, moderate, or marked. Conditional logistic regression analysis was performed to estimate the associations (OR) of BPU categories (moderate or marked vs. minimal to mild or photopenic) and breast cancer risk, adjusted for other risk factors. The median age was 60.2 years (range 38-86 years) for cases vs. 60.2 years (range 38-88 years) for controls (p = 0.88). Women with moderate or marked BPU had a 3.4-fold (95 % CI 1.6-7.3) and 4.8-fold (95 % CI 2.1-10.8) increased risk of breast cancer, respectively, compared with women with photopenic or minimal to mild BPU, for two radiologists. The results were similar after adjustment for BI-RADS density (OR 3.3 [95 % CI 1.6-7.2] and OR 4.6 [95 % CI 2.1-10.5]) or postmenopausal hormone use (OR 3.6 [95 % CI 1.7-7.7] and OR 5.0 [95 % CI 2.2-11.4]). The association of BPU with breast cancer remained in analyses limited to postmenopausal women only (OR 3.8 [95 % CI 1.5-9.3] and OR 4.1 [95 % CI 1.6-10.2]) and invasive breast cancer cases only (OR 3.6 [95 % CI 1.5-8.8] and OR 4.4 [95 % CI 1.7-11.1]). Variable BPU was observed among women with similar mammographic density; the distribution of BPU categories differed across density categories (p factor for breast cancer.

    To determine whether induced abortion (IA) increases breast cancer (BC) risk. A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency- matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. The results suggest that a history of induced abortions may not increase the risk of breast cancer.

    Male breast cancer is rare, comprising only 1% of all mammary cancers; invasive ductal carcinoma is by far the commonest subtype in both men and women. Though lobular breast cancer is the second most common subtype seen in women, such cancers are extremely uncommon in men, and this is likely related to the lack of lobular development in the male breast. Thus, due to the rarity of this subtype among breast cancers, compounded by the overall rarity of breast cancer in men, current understanding of the pathogenesis of this disease and its management is largely derived from case series and extrapolation of information from the larger cohort of female patients. This paper provides a systematic review on invasive lobular carcinoma of the male breast in the context of an illustrative case study. A comprehensive analysis of the National Cancer Institute’s Surveillance, Epidemiology, and End Results Data 1973–2013 leading to an exploration of the pathogenesis, epidemiology, clinical presentation, diagnosis, tumor characteristics, and management of lobular breast carcinoma in men is also discussed. Lobular subtype of breast cancer remains an enigmatic elusive disease that needs additional research to unravel its overall pathogenesis and molecular profile to provide insight for improved therapeutic management options.

    Attributions of causality are common for many diseases, including breast cancer. The risk of developing breast cancer can be reduced by modifications to lifestyle and behaviours to minimise exposure to specific risk factors, such as obesity. However, these modifications will only occur if women believe that certain behaviours/lifestyle factors have an impact on the development of breast cancer. The Breast Cancer, Environment and Employment Study is a case-control study of breast cancer conducted in Western Australia between 2009 and 2011. As part of the study 1109 women with breast cancer and 1633 women without the disease completed a Risk Perception Questionnaire in which they were asked in an open-ended question for specific cause/s to the development of breast cancer in themselves or in others. The study identified specific causal beliefs, and assessed differences in the beliefs between women with and without breast cancer. The most common attributions in women without breast cancer were to familial or inherited factors (77.6%), followed by lifestyle factors, such as poor diet and smoking (47.1%), and environmental factors, such as food additives (45.4%). The most common attributions in women with breast cancer were to mental or emotional factors (46.3%), especially stress, followed by lifestyle factors (38.6%) and physiological factors (37.5%), particularly relating to hormonal history. While the majority of participants in this study provided one or more causal attributions for breast cancer, many of the reported risk factors do not correspond to those generally accepted by the scientific community. These misperceptions could be having a significant impact on the success of prevention and early detection programs that seek to minimise the pain and suffering caused by this disease. In particular, women who have no family history of the disease may not work to minimise their exposure to the modifiable risk factors.

    Breast cancer is the most common female cancer and the commonest cause of death due to cancer for women in Malaysia. This study was performed to identify the relationship with lifestyle factors. A case-control study was conducted among females with breast cancer who came for treatment to the Breast Clinic Hospital Kuala Lumpur in July until September 2004. A total of 203 female patients were recruited as cases along with 203 patients who attended the Outpatient Clinic, Hospital Kuala Lumpur during the study period as the controls. The study showed women who did not exercise regularly to have four times higher risk (adjusted odds ratio is 3.49, 95% CI is 1.84 to 6.62) compared to those who exercised regularly. Women with a high fat diet were also at elevated risk (adjusted odds ratio 3.84, 95% CI is 1.20 to 12.34) compared to those consuming a low fat diet. Women without breast cancer generally had a longer duration of lifetime lactation with a median of thirty-three months compared to women with breast cancer (twenty months, p<0.05). Women who did not take oral contraceptive pills but had breast-fed their child have a 56.0% lower risk (crude odds ratio 0.44, CI is 0.22 to 0.87) compared to women who did not take oral contraceptive pill and also did not breast-feed their child. If they had breast fed for thirteen months and above, they faced a 61.0% lower risk (crude odds ratio 0.39, 95% CI is 0.17 to 0.87). There was a significant inverse trend for lifetime lactation and breast cancer risk. In conclusion certain life styles of women are associated with a higher risk of breast cancer development. Therefore, the promotion of a healthy life style should be emphasized.

    Objective: To find the incidence of malignancy in females presenting with breast lumps in surgical out patient and to find out the age related incidence of benign and malignant diseases in these patients. Patients and Methods: All cases reporting to surgical outdoor with breast lumps were included and underwent investigation for the breast lumps to determine the histopathological diagnosis. Results: A total of 277 cases were studied. 24.2% breast lumps were malignant and 75.8% were benign. The incidence of malignancy increases from 0% in 2nd decade to 38.9% in 5th and 100% in 9th decade of life. The probability of diagnosing a breast lump as a malignant is one in three in 4th decade, two in five in 5th decade and more than one in two there after. Fibrocystic disease (33.8%) and Fibro adenoma (27.1%) was the commonest finding among the benign lumps. Among malignant lumps infiltrating duct carcinoma (68.7%) is the commonest finding. Conclusion: There is a significantly high incidence of malignant breast lumps after the 3rd decade of life and it increases subsequently. It is recommended that the surgeon managing a case of breast lump in a patient above 30 years should be highly suspicious and cautious so that early detection and management of malignant lumps be carried out.

    Full Text Available Background. Vietnam has a low age-standardized incidence of breast cancer, but the incidence is rising rapidly with economic development. We report data from a matched case-control study of risk factors for breast cancer in the largest cancer hospital in Vietnam. Methods. 492 incident breast cancer cases unselected for family history or age at diagnosis and 1306 control women age 25–75 were recruited from the National Cancer Hospital (BVK, Hanoi. Structured interviews were conducted and pathology data was centrally reported at the National Cancer Hospital of Vietnam, in Hanoi. Results. Our analysis included 294 matched pairs. Mean age at diagnosis was 46.7 years. Lower mean parity, older age at first parity, increasing weight and BMI at age 18, and increasing BMI at diagnosis were positively correlated with breast cancer cases compared to controls. Age at first menarche and duration of breastfeeding were not statistically different between cases and controls. Conclusions. In this study we demonstrate that breast cancer in Vietnam is associated with some but not all of the published risk factors from Western populations.

    Breast cancer is the most common cancer in females worldwide, and the second leading cause of cancer deaths in women. The incidence is on the rise in India, and breast cancer is the second most common malignancy in Indian women. To assess the risk factors for breast cancer patients living in Bhopal. This case-control study was conducted in Bhopal urban agglomerate for a period of a year from October 2008 to August 2009. Demographic data and reproductive risk factor related information was collected using a structured questionnaire with analyses by Epi-info and SPSS 16. A history of oral contraceptive pill use (OR=2.77, 95% CI: 1.15-6.65), history of not having breastfeeding (OR=3.49, 95% CI:1.22-9.97), over weight (OR=0.11, 95%CI:0.02-0.49), obese women (OR=0.24, 95%CI: 0.06-0.88) and family history of breast cancer (OR=3.89, 95% CI: 1.01-14.92) were associated significantly with the occurrence of breast cancer on multivariate analysis. The findings of the present study suggests that positive family history of breast cancer and history of using OCP may be the epigenetic factors promoting the occurrence of breast cancer while breastfeeding reduces the possibility of acquiring breast cancer.

    Full Text Available Abstract Background Breast cancer is the most common form of malignancy affecting women worldwide. It is also the leading cancer in females in Cyprus, with approximately 400 new cases diagnosed annually. It is well recognized that genetic variation as well as environmental factors modulate breast cancer risk. The main aim of this study was to assess the strength of associations between recognized risk factors and breast cancer among Cypriot women. This is the first epidemiological investigation on risk factors of breast cancer among the Cypriot female population. Methods We carried out a case-control study, involving 1,109 breast cancer patients and a group of 1,177 controls who were recruited while participating in the National screening programme for breast cancer. Information on demographic characteristics and potential risk factors were collected from both groups during a standardized interview. Logistic regression analysis was used to assess the strength of the association between each risk factor and breast cancer risk, before and after adjusting for the possible confounding effect of other factors. Results In multivariable models, family history of breast cancer (OR 1.64, 95% CI 1.23, 2.19 was the strongest predictor of breast cancer risk in the Cypriot population. Late menarche (OR 0.64, 95% CI 0.45, 0.92 among women reaching menarche after the age of 15 vs. before the age of 12 and breastfeeding (OR 0.74, 95% CI 0.59, 0.92 exhibited a strong protective effect. In the case of breastfeeding, the observed effect appeared stronger than the effect of pregnancy alone. Surprisingly, we also observed an inverse association between hormone replacement therapy (HRT although this may be a product of the retrospective nature of this study. Conclusion Overall the findings of our study corroborate with the results of previous investigations on descriptive epidemiology of risk factors for breast cancer. This investigation provides important background

    Health inequalities have increased over the last 30 years. Our goal was to investigate the relationship between low individual socioeconomic status and poor breast cancer prognosis. Our hypothesis was: low socioeconomic status patients have a higher risk of being diagnosed with late stage breast cancer than high socioeconomic status ones due to delayed diagnosis. We conducted a matched case-control study on 619 women with breast cancer, living in the Hérault, a French administrative area. Both Cases and Controls were recruited among invasive cases diagnosed in 2011 and 2012 and treated in Hérault care centers. Cases were defined as patients with advanced stages. Controls were composed of early stage patients. Individual socioeconomic status was assessed using a validated individual score adapted to the French population and health care system. We observed that low socioeconomic status patients have a 2-fold risk of having late stage breast cancer regardless of cancer characteristics and detection mode (screening vs. clinical signs). One reason explaining those results could be that low socioeconomic status patients have less regular follow-up which can lead to later and poorer diagnosis. Follow-up is improved for women with a better awareness of breast cancer. Health policy makers could reduce health inequalities by reducing the delay in breast cancer diagnosis for low socioeconomic status women. © The Author 2016.

    Full Text Available Abstract Background Tobacco smoke exposure may be associated with increased breast cancer risk, although the evidence supporting the association is inconclusive. We conducted a case-control study in Delaware, incorporating detailed exposure assessment for active and secondhand smoke at home and in the workplace. Methods Primary invasive breast cancer cases diagnosed among female Delaware residents, ages 40–79, in 2000–2002 were identified through the Delaware cancer registry (n = 287. Delaware drivers license and Health Care Finance Administration records were used to select age frequency-matched controls for women Results A statistically significant increased risk of breast cancer was observed for ever having smoked cigarettes (odds ratio = 1.43, 95% confidence interval = 1.03–1.99. However, there was no evidence of a dose-response relationship between breast cancer risk and total years smoked, cigarettes per day, or pack-years. Neither residential nor workplace secondhand smoke exposure was associated with breast cancer. Recalculations of active smoking risks using a purely unexposed reference group of women who were not exposed to active or secondhand smoking did not indicate increased risks of breast cancer. Conclusion These findings do not support an association between smoking and breast cancer.

    Strontium has been widely used in industries like electronic and pharmacy. It has a carcinogenic potential, however, and no study has been conducted to evaluate its effects on cancer risk. The aim of this study was to explore the possible association between strontium and breast cancer risk in a case-control study including 240 incident invasive breast cancer patients and 246 age-matched controls. We measured the urinary concentrations of strontium by inductively coupled plasma mass spectrometry, and conducted face-to-face interviews to obtain information on potential breast cancer risk factors. Multivariable analysis was used to estimate the association. Creatinine-adjusted levels [median (25th, 75th) {mu}g/g] of strontium were 155.59 (99.05, 230.70) in the breast cancer patients and 119.62 (81.97, 163.76) in the controls. Women in the highest tertile of strontium showed 124% increased risk of breast cancer, when compared with those in the lowest tertile after adjustment for the potential risk factors [OR (95% CI): 2.24 (1.42-3.81)]. This association was particularly strong for HER2 positive breast cancer [OR (95% CI): 10.92 (3.53-33.77)], and only occurred among premenopausal women. These results suggest a potential role of strontium in the development of breast cancer and urge further studies on the environmental contamination and the physiological and pathological mechanisms of strontium.

    The use of Macrolane™ seems to have several advantages compared to the other standard methods for breast augmentation: it is faster, less invasive, and requires only local anesthesia. Nevertheless, various complications associated with the use of Macrolane™ have been described, e.g., encapsulated lumps in breast tissue, infection, and parenchymal fibrosis. We report the results of our case series study on the clinical and imaging evaluations of patients who came to our attention after breast augmentation with Macrolane™ injection and evaluate the effect of this treatment on breast cancer screening procedures. Between September 2009 and July 2010, seven patients, treated elsewhere with intramammary Macrolane™ injection for cosmetic purposes, presented to our institution complaining of breast pain. In all patients, Macrolane™ had been injected under local anesthesia in the retromammary space through a surgical cannula. On mammography, nodules appeared as gross lobulated radiopacities with polycyclic contours. On breast ultrasound, the nodules showed hypo-anaechogenic cystlike features. In all cases, image analysis by the radiologist was hindered by the presence of the implanted substance, which did not allow the complete inspection of the whole breast tissue. From our experience, although safe in other areas, injection of Macrolane™ into breast tissue cannot be recommended at this time. Our study, along with other reports, supports the need to start a clinical trial on the use of injectable fillers in the breast to validate their safety and effectiveness.

    This study aimed to investigate risk factors associated with breast cancer among Han Chinese women in northern and eastern China. A matched case-control study involving 1489 patients with breast cancer and 1489 controls was conducted across 21 hospitals in 11 provinces in China, from April 2012 to April 2013. We developed a structured questionnaire to record information from face-to-face interviews with participants. Student's t-tests, Pearson's chi-square tests, and univariate and multivariate conditional logistic regression analyses were used to identify variables with significant differences between the case and control groups. Ten variables were identified (P ratio, menopause, family history of breast cancer, present life satisfaction, sleep satisfaction, milk products, behavior prevention scores, and awareness of breast cancer. We identified a comprehensive range of factors related to breast cancer, among which several manageable factors may contribute to breast cancer prevention. Further prospective studies concerning psychological interventions, sleep regulation, health guidance, and physical exercise are required. A screening model for high-risk populations should be put on the agenda.

    Two case studies are used to discuss topical issues current in follow-up management of patients with early stage breast cancer. These issues include the role of screening and diagnostic bone scintigraphy and patient self-advocacy in clinical management. Breast cancer is common. Standard clinical practice in Australia for patients treated for early stage carcinoma of the breast is regular follow-up, usually lasting 5 years, and often 10 years. There are numerous benefits for patients receiving regular clinical checkups post-treatment of breast cancer. However, the three prime objectives are early detection of recurrence, assessment of treatment-related morbidity, and provision of psychological support. Not surprisingly, a variety of intercurrent clinical events can occur in a population of post-treatment breast cancer patients on long-term follow-up. In this article we describe two interesting cases, each presenting with a solitary new destructive rib lesion highly suggestive of a first clinical diagnosis of metastatic breast cancer. Subsequent biopsy revealed the lesions to be benign. Copyright (1999) Blackwell Science Pty Ltd

    This study was designed to explore risk factors for breast cancer with emphasis on the detection of clinical markers of the hormonal imbalance during the perimenarche. Three hundred and thirty women diagnosed with breast cancer and 346 population controls were identified and interviewed in Girona, Spain between 1986 and 89. Cases were more likely than controls to have had long menstrual periods in the first 5 years after menarche [odds ratio (OR) = 3.0], to experience menopause at a late age (OR = 1.5) and to report acne during adolescence (OR = 1.6). Family history of breast cancer was associated with an increased risk (OR = 2.3). Cases reported a lower use of drug treatments for anxiety and sleep disorders than controls. Moderate alcohol drinkers and smokers were at lower risk for breast cancer. No statistically significant association with breast cancer was observed for number of children, age at last pregnancy, oral contraceptive use, hormonal treatment after menopause and weight perception during the teenage years. Hormonal changes in the years following menarche may be relevant to breast cancer risk. The roles of menstrual period length and acne during adolescence should be further explored.

    Background parenchymal uptake (BPU), which refers to the level of Tc-99m sestamibi uptake within normal fibroglandular tissue on molecular breast imaging (MBI), has been identified as a breast cancer risk factor, independent of mammographic density. Prior analyses have used subjective categories to describe BPU. We evaluate a new quantitative method for assessing BPU by testing its reproducibility, comparing quantitative results with previously established subjective BPU categories, and determining the association of quantitative BPU with breast cancer risk. Two nonradiologist operators independently performed region-of-interest analysis on MBI images viewed in conjunction with corresponding digital mammograms. Quantitative BPU was defined as a unitless ratio of the average pixel intensity (counts/pixel) within the fibroglandular tissue versus the average pixel intensity in fat. Operator agreement and the correlation of quantitative BPU measures with subjective BPU categories assessed by expert radiologists were determined. Percent density on mammograms was estimated using Cumulus. The association of quantitative BPU with breast cancer (per one unit BPU) was examined within an established case-control study of 62 incident breast cancer cases and 177 matched controls. Quantitative BPU ranged from 0.4 to 3.2 across all subjects and was on average higher in cases compared to controls (1.4 versus 1.2, p Quantitative BPU was strongly correlated with subjective BPU categories (Spearman's r = 0.59 to 0.69, p quantitative BPU measure, assessed by intraclass correlation, was 0.92 and 0.98, respectively. Quantitative BPU measures showed either no correlation or weak negative correlation with mammographic percent density. In a model adjusted for body mass index and percent density, higher quantitative BPU was associated with increased risk of breast cancer for both operators (OR = 4.0, 95% confidence interval (CI) 1.6-10.1, and 2.4, 95% CI 1.2-4.7).

    Full Text Available Background: Neonatal jaundice, especially breast feeding jaundice is one of the most common causes of neonatal readmission during the first month of life. Breast feeding jaundice may be due to decreased milk intake with dehydration and/or reduced caloric intake.  The aim of this Study was to determine maternal risk factors of breast feeding jaundice in order to prevent it than before.Methods: This case- control study was performed at Bahrami University Hospital, Tehran, Iran and involved 75 term exclusively breast fed newborns admitted for hyperbilirubinemia, with a weight loss greater than 7%, with one positive lab data as: serum Na≥ 150meq/lit, urine specific gravity> 1012, serum urea≥ 40mgr/dl, without assigned cause for hyperbilirubinemia. They were compared with 75 matched controls with weight loss less than 7%, without dehydration and a known cause of hyperbilirubinemia.Results: In comparison with control group, in neonates with breast feeding jaundice, inappropriate feeding practice (P<0.033, delayed onset of lactation (P<0.0001, inverted nipple (P<0.001 were significantly higher. In our study, there was no significant difference between two groups in education level of mother, learning breast feeding practice before and after delivery, method of delivery (cesarean or vaginal delivery, primiparity or multiparity and use of supplements (water or glucose water.Conclusion: This study shows need for special attention and follows up of mothers and neonates at risk for breast feeding jaundice, especially those with inverted nipples or undergraduate for successful breast feeding. On the other hand this study shows encouraging mothers for early lactation especially in the first hour of life decreases the risk for this kind of jaundice.

    Patient-reported outcomes and quality of life following mastectomy are not well understood. This study evaluates the quality of life following surgery for breast cancer and compares outcomes following breast-conserving surgery versus total mastectomy with or without reconstruction. A case-controlled cross-sectional study was conducted using the validated BREAST-Q™ questionnaire and a study-specific questionnaire to determine patient's views about surgical outcomes. Questionnaires were completed by patients following breast-conserving surgery and total mastectomy with or without reconstruction and by controls without breast cancer. A one-way ANOVA was used to compare mean BREAST-Q™ scores between groups and post hoc analysis using Tukey's and Kruskal-Wallis tests. BREAST-Q™ questionnaires were completed by 400 women (123 controls, 97 breast conservations, 93 mastectomies without reconstruction, 87 mastectomies with reconstruction). Women who had undergone mastectomy and reconstruction had higher scores in satisfaction with breast and sexual well-being domains compared with women who had breast-conserving surgery, and women who had total mastectomy without reconstruction had the lowest scores in these two domains. There was no difference in psychosocial well-being between the groups. Women who had undergone breast-conserving surgery scored the lowest in the physical well-being chest domain and the majority reported breast asymmetry. Our study suggests that women who undergo total mastectomy and breast reconstruction for cancer achieve a quality-of-life outcome that is at least as good as that following breast-conserving surgery. Furthermore, breast conservation has been found to be associated with lower physical well-being (i.e., more pain and discomfort) in the chest area and poorer sexual well-being outcomes.

    Due to their lipophilic properties, dioxins (PCDD/PCDFs) and other organohalogen compounds bioaccumulate in the food chain, with diet accounting for over 90% of non-occupational exposures. To date, few epidemiologic studies have examined the relationship between dioxins and breast cancer in human populations. Most have examined risks in occupational cohorts or in populations exposed to dioxins from the Seveso accident6-8. Results from these studies have been conflicting and have largely been limited by a lack of individual-level measures of exposure, small numbers of cases, and inability to account for established breast cancer risk factors. Very little is known about the potential health effects of low-level environmental dioxin contamination. We present data on PCDD/PCDFs, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in adipose tissues of women participating in a breast cancer case-control study centered in the San Francisco Bay Area. In addition, we examine distributions of these chemicals in breast and abdominal adipose of women undergoing mastectomies with concurrent breast reconstruction. If concentrations were equivalent, use of abdominal adipose would greatly enhance the pool for controls for future epidemiological studies.

    The etiology of breast cancer is not well understood and the role of occupational exposures in breast carcinogenesis is still uncertain. The population-based case-control study included 2,386 incident breast cancer cases diagnosed in 2000-2003, and 2,502 controls. Lifetime occupational histories and information on other potential breast cancer risk factors were obtained through personal interviews. Conditional logistic regression analyses calculated odds ratios (ORs) associated with various occupations and industries after control for potential confounders. We found statistically significant excesses of breast cancer among engineers (OR=2.0; 95% CI: 1.0-3.8), economists (2.1; 1.1-3.8), sales occupations-retail (1.2; 1.0-1.5), and other sales occupations (1.2; 1.0-1.5). Industries showing significantly elevated risks included special trade contractors (2.2; 1.2-4.3), electronic and electric equipment manufacturers (1.7; 1.1-2.7); and public administration/general government n.e.c. (2.7; 1.3-5.7). Each of these findings was supported by a statistically significant positive trend for duration of employment (Pelectronic and electric equipment manufacturing industry and for the occupations with potential exposure to magnetic fields deserve further evaluation.

Aims: To conduct a case-control study comparing disease control, cosmesis, and complications in patients with EBC undergoing APBI using multicatheter interstitial brachytherapy vs those receiving conventional whole breast radiotherapy (WBRT. Settings and Design: Women with EBC fulfilling the American Brachytherapy Society (ABS criteria were selected as ′cases′ if treated with APBI or as ′controls′ if offered WBRT during the period from May 2000 to December 2004. Materials and Methods: APBI patients were treated with high-dose-rate brachytherapy (HDR to a dose of 34 Gy/10#/6-8 days. WBRT was delivered to the whole breast to a dose of 45 Gy/25# followed by tumor bed boost, either with electrons (15 Gy/6# or interstitial brachytherapy (HDR 10 Gy/1#. Results: At the median follow-up of 43.05 months in APBI and 51.08 months in WBRT there was no difference in overall survival (OS, disease-free survival (DFS, late arm edema, and symptomatic fat necrosis between the two groups. However, APBI resulted in increase in mild breast fibrosis at the tumor bed. Telangiectasias were observed in three patients of the APBI group. The cosmetic outcome was significantly better in the APBI group as compared to the WBRT group (P = 0.003. Conclusions: This study revealed equivalent locoregional and distant disease control in the two groups. APBI offered better overall cosmetic outcome, though at the cost of a slight increase in mild breast fibrosis and telangiectasias.

    Breast masses occur in men far less commonly than women and are infrequently subjected to fine-needle aspiration (FNA) biopsy. Papillary lesions of the male breast are rare and are comprised of a spectrum of lesions ranging from papillary hyperplasia in gynecomastia to invasive papillary carcinoma. The following study describes the cytomorphology of papillary breast lesions in 11 men. The patients ranged in age from 23 to 78 years old and each presented with an unilateral subareolar or periareolar breast mass that varied in size from 0.5 to 3 cm. Two patients presented with bloody nipple discharge. Archival material (8-year period) from FNA biopsies of papillary lesions of the male breast was reviewed. The reviewed cases were correlated with appropriate clinicopathologic follow-up. The smears had variable cellularity but all showed papillary clusters of mammary epithelial cells with and without fibrovascular cores. Single epithelial cells with a high nuclear-to-cytoplasmic ratio and eccentric nuclei were seen in all smears; however, these were more numerous in cases of adenocarcinoma. Hemosiderin-laden macrophages were present in all cases. Nipple discharge was seen only in the 2 benign lesions. All adenocarcinomas occurred in older men. The only cytologic criteria that differentiated benign from malignant papillary lesions were marked cellularity and the presence of abundant 3-dimensional clusters. To the best of the authors' knowledge, the current series is the largest in the English literature to date that examines the cytomorphologic features of papillary breast lesions in men.

A comparative study of 144 breast cancer survivors and 125 women without previous history of cancer was carried out. Neuropsychiatric symptomatology was assessed retrospectively using standardized psychiatric examinations (Mini International Neuropsychiatric Interview, Watson's Post-Traumatic Stress Disorder Inventory) over three successive periods, 'before cancer' (from childhood to 3 years before the interview), 'around the cancer event' (the last 3 years including the time of diagnosis and treatment), and 'currently' (the last 2 weeks). Increased rates of anxiety and mood disorders were observed following a diagnosis of breast cancer compared with controls (generalized anxiety disorder (GAD) and major depressive disorder (MDD); 10.4 vs 1.6% and 19.4 vs 8.8%, respectively). The cancer disease promoted the development of dysthymia (n=4 new cases/6 two-year prevalent cases) and PTSD (7/7) and the re-emergence of MDD (n=21 relapses/28 three-year prevalent cases) and GAD (10/15). No improvement in serious mood disorders such as MDD (16.0 vs 7.2%) and dysthymia (4.2 vs 0%) was reported at the time of interview, more than 1.75 years (median time) after the cancer surgery, the prevalence being 2-4 times greater in breast cancer survivors than in controls. Despite significant advances in treatment, a diagnosis of breast cancer is highly associated with various forms of psychopathology, regardless of psychiatric history, with symptoms persisting after treatment. These results may assist clinicians in planning mental healthcare for women with breast cancer.

    Unhealthy dietary habits can increase the risk for serious medical conditions, such as cancer, yet the association between diet and breast cancer remains unclear. We investigated whether individual diets based on their inflammatory potential are associated with postmenopausal breast cancer risk by employing an energy-adjusted dietary inflammation index. In a German population-based case-control study, 2887 postmenopausal breast cancer patients (aged 50-74 years, first diagnosed between 2002 and 2005) and 5512 healthy age-matched controls provided information on dietary habits for the year prior to diagnosis (cases) or recruitment (controls) using a 176-items food frequency questionnaire. Associations between the energy-adjusted dietary inflammation index (E-DII) score (both as continuous variable and in quintiles) and risk for breast cancer were assessed using conditional logistic regression adjusted for potential confounders. No significant associations between the E-DII score and postmenopausal breast cancer risk were observed (adjusted OR Q5 vs Q1: 1.01, 95% CI: 0.86-1.17). Associations did not differ by estrogen receptor/progesterone receptor status (ER + PR+: adjusted OR Q5 vs Q1: 1.06, 95% CI: 0.88-1.27; ER + or PR+: OR Q5 vs Q1: 1,07, 95% CI: 0.79-1.45; ER-PR-: OR Q5 vs Q1: 0.87 95% CI: 0.63-1.20). Our results regarding E-DII are consistent with previous studies reporting a lack of association between C-reactive protein, a marker of systemic inflammation, and postmenopausal breast cancer risk. The findings may reflect a real absence of association between dietary inflammatory potential and postmenopausal cancer risk or an underestimation of association due to recall bias. Further investigation is warranted in cohort studies. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Pregnancy and fertility issues are substantial concerns for the young breast cancer survivor, yet the available literature is hampered by a lack of prospective clinical studies and meaningful long-term outcome data. A lack of reliable information often leads to physician discomfort and patients may be left to navigate the world of fertility preservation and reproductive technology on their own. This case exemplifies some of the many issues that breast cancer survivors may face and adds another dimension to the survivor's dilemma; once fertility options have been preserved, what is the best method to sustain the pregnancy--self or surrogate? For many, the goal of balancing optimal treatment and long-term survival with restoration of a complete quality of life, including childbearing, may be attainable. This discussion highlights the importance of offering young breast cancer patients an opportunity to discuss these issues with their health care providers prior to initiating therapy.

    Full Text Available Abstract Background Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. Methods All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. Results In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004. Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR = 3.21, 95% confidence interval (CI: 1.15–8.47]. Conclusion The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

    Oestrogen receptor α, which mediates the effect of oestrogen in target tissues, is genetically polymorphic. Because breast cancer development is dependent on oestrogenic influence, we have investigated whether polymorphisms in the oestrogen receptor α gene (ESR1) are associated with breast cancer risk. We genotyped breast cancer cases and age-matched population controls for one microsatellite marker and four single-nucleotide polymorphisms (SNPs) in ESR1. The numbers of genotyped cases and controls for each marker were as follows: TA n , 1514 cases and 1514 controls; c.454-397C → T, 1557 cases and 1512 controls; c.454-351A → G, 1556 cases and 1512 controls; c.729C → T, 1562 cases and 1513 controls; c.975C → G, 1562 cases and 1513 controls. Using logistic regression models, we calculated odds ratios (ORs) and 95% confidence intervals (CIs). Haplotype effects were estimated in an exploratory analysis, using expectation-maximisation algorithms for case-control study data. There were no compelling associations between single polymorphic loci and breast cancer risk. In haplotype analyses, a common haplotype of the c.454-351A → G or c.454-397C → T and c.975C → G SNPs appeared to be associated with an increased risk for ductal breast cancer: one copy of the c.454-351A → G and c.975C → G haplotype entailed an OR of 1.19 (95% CI 1.06–1.33) and two copies with an OR of 1.42 (95% CI 1.15–1.77), compared with no copies, under a model of multiplicative penetrance. The association with the c.454-397C → T and c.975C → G haplotypes was similar. Our data indicated that these haplotypes were more influential in women with a high body mass index. Adjustment for multiple comparisons rendered the associations statistically non-significant. We found suggestions of an association between common haplotypes in ESR1 and the risk for ductal breast cancer that is stronger in heavy women

    Background Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. Methods Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer between 1988 and 1995 and 721 controls. Telephone interviews asked about product use, beliefs about breast cancer etiology, and established and suspected breast cancer risk factors. To evaluate potential recall bias, we stratified product-use odds ratios by beliefs about whether chemicals and pollutants contribute to breast cancer; we compared these results with odds ratios for family history (which are less subject to recall bias) stratified by beliefs about heredity. Results Breast cancer risk increased two-fold in the highest compared with lowest quartile of self-reported combined cleaning product use (Adjusted OR = 2.1, 95% CI: 1.4, 3.3) and combined air freshener use (Adjusted OR = 1.9, 95% CI: 1.2, 3.0). Little association was observed with pesticide use. In stratified analyses, cleaning products odds ratios were more elevated among participants who believed pollutants contribute "a lot" to breast cancer and moved towards the null among the other participants. In comparison, the odds ratio for breast cancer and family history was markedly higher among women who believed that heredity contributes "a lot" (OR = 2.6, 95% CI: 1.9, 3.6) and not elevated among others (OR = 0.7, 95% CI: 0.5, 1.1). Conclusions Results of this study suggest that cleaning product use contributes to increased breast cancer risk. However, results also highlight the difficulty of distinguishing in retrospective self-report studies between valid associations and the influence of recall bias.

    Breast cancer has emerged as a leading site of cancer among women in India. Fine needle aspiration cytology (FNAC) has been routinely applied in assessment of breast lesions. Cytological evaluation in breast lesions is subjective with a "gray zone" of 6.9-20%. Quantitative evaluation of nuclear size, shape, texture, and density parameters by morphometry can be of diagnostic help in breast tumor. To apply nuclear morphometry on cytological breast aspirates and assess its role in differentiating between benign and malignant breast lesions with derivation of suitable cut-off values between the two groups. The present study was a descriptive cross-sectional hospital-based study of nuclear morphometric parameters of benign and malignant cases. The study included 50 benign breast disease (BBD), 8 atypical ductal hyperplasia (ADH), and 64 carcinoma cases. Image analysis was performed on Papanicolaou-stained FNAC slides by Nikon Imaging Software (NIS)-Elements Advanced Research software (Version 4.00). Nuclear morphometric parameters analyzed included 5 nuclear size, 2 shape, 4 texture, and 2 density parameters. Nuclear morphometry could differentiate between benign and malignant aspirates with a gradually increasing nuclear size parameters from BBD to ADH to carcinoma. Cut-off values of 31.93 μm 2 , 6.325 μm, 5.865 μm, 7.855 μm, and 21.55 μm for mean nuclear area, equivalent diameter, minimum feret, maximum ferret, and perimeter, respectively, were derived between benign and malignant cases, which could correctly classify 7 out of 8 ADH cases. Nuclear morphometry is a highly objective tool that could be used to supplement FNAC in differentiating benign from malignant lesions, with an important role in cases with diagnostic dilemma.

    Medullary carcinoma of the breast is a rare type breast cancer, and shows peculiar clinical features. In a series of 460 cases of breast cancer operated on at the hospital from 1975 to 2004, twelve (2.6%) cases were diagnosed as medullary carcinoma of the breast by postoperative pathological study. When the specimens from the twelve tumors were reevaluated according to the Ridolfi's subtype classification, six tumors were classified into typical medullary carcinoma (TMC) and the remaining six tumors into atypical medullary carcinoma (AMC). On mammography these tumors were visualized as homogeneously enhancing oval masses without calcification and the boundary was comparatively well-defined. US demonstrated well-defied masses with a heterogeneous, hypoechoic texture and with reinforcement of posterior echoes. The rate of lymph node metastasis was 33.3% in medullary carcinomas which was not significantly different from that of infiltrative ductal carcinomas experienced during the same period. The rate of a positivity of a hormone receptor was 8.3% in medullary carcinomas which was low in predominance in comparison with that of infiltrative ductal carcinomas. The positive rate for a HER2/neu (above2+) by the IHC method was 58%. An average observation period is 11 years, and all patients are alive. (author)

    Margaret*, a 56 year-old Caucasian Stage III breast cancer survivor, participated in a 5 week occupational therapy pilot program, called Take Action. This program was designed for breast cancer survivors who self-reported changes in cognitive function following completion of chemotherapy. The goals of the program were to improve participants' knowledge and use of strategies to enhance occupational performance and to improve satisfaction and performance of meaningful daily activities or occupations. Through a client-centered and evidence-based approach, this case study highlights the importance of incorporating the survivors' sense of self into an occupation-based intervention. Occupational therapists play an important role in facilitating exploration of sense of self in the survivorship phase of care to support occupational performance in self care, productivity, work, leisure and social participation. This case study highlights the important work of redefining oneself in the survivorship phase of care. (*denotes name change).

    Breast cancer has been increased in South East Asia countries, but there are limited data for breast cancer risk factors in these countries. To clarify the risk for breast cancer among the Malaysian women, a matched case-control study was conducted. Between October 2009 and April 2010, a survey was prospectively conducted among women admitted to clinics of Penang General Hospital for examination and/or treatment by using a questionnaire. Therefore, characteristics of patients diagnosed with breast cancer (n=150) were compared with control cases (n=150) admitted to hospital for non-neoplastic, non-hormone related diseases. Family history of a distant relative with breast cancer (OR=2.84), history of first-degree relatives with breast cancer (OR=2.95), history of benign breast disease (OR=2.43), menstrual irregularity (OR=4.24), and use of oral contraceptive pills (OCP) (OR=2.15) were found to be significant risk factors for breast cancer in our population. Furthermore, education more than 11 years (OR=0.40), breastfeeding (OR=0.50), being employed (OR=0.45) and practicing low fat diet (OR=0.53) were strongly protective against breast cancer development. The results emphasize the importance of conducting a series of awareness campaigns that highlights the protective role of longer breastfeeding period against breast cancer and the negative relationships between OCP use and high fat diet with this disease.

    Full Text Available Abstract Background The effect of antioxidants on breast cancer is still controversial. Our objective was to assess the association between antioxidants and breast cancer risk in a large population-based case-control study. Methods The study population included 2,362 cases with pathologically confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal and 2,462 controls in Canada. Intakes of antioxidants from diet and from supplementation as well as other potential risk factors for breast cancer were collected by a self-reported questionnaire. Results Compared with subjects with no supplementation, 10 years or longer supplementation of zinc had multivariable-adjusted odds ratios (OR and 95% confidence intervals (CI of 0.46 (0.25-0.85 for premenopausal women, while supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc had multivariable-adjusted ORs (95% CIs of 0.74 (0.59, 0.92, 0.58 (0.36, 0.95, 0.79 (0.63-0.99, 0.75 (0.58, 0.97, and 0.47 (0.28-0.78, respectively, for postmenopausal women. No significant effect of antioxidants from dietary sources (including beta-carotene, alpha-carotene, lycopene, lutein and zeaxanthin, vitamin C, vitamin E, selenium and zinc or from supplementation less than 10 years was observed. Conclusions This study suggests that supplementation of zinc in premenopausal women, and supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer. However, we were unable to determine the overall effect of total dose or intake from both diet and supplement.

    Patients with pathologic processes of the breast commonly present in the Emergency Department (ED). Familiarity with the imaging and management of the most common entities is essential for the radiologist. Additionally, it is important to understand the limitations of ED imaging and management in the acute setting and to recognize when referrals to a specialty breast center are necessary. The goal of this article is to review the clinical presentations, pathophysiology, imaging, and management of emergency breast cases and common breast pathology seen in the ED.

    Older adults are underrepresented in medical research for many reasons, including recruitment difficulties. Recruitment of older adults for research studies is often a time-consuming process and can be more challenging when the study involves older adults with unique exposures to traumatic events and from minority groups. The current article provides a brief overview of (a) challenges encountered while recruiting aging women Holocaust survivors for a case control study and (b) strategies used for meeting those challenges. The case group comprised women Holocaust survivors who were recently diagnosed with breast cancer and the control group comprised healthy women from a Holocaust-survivor community in Israel.

    Current studies have shown that fast weight gain may be more important than body mass index on the incidence of breast cancer. The aim of this study was to evaluate the association between body weight and breast cancer. This was a case-control study nested in a cohort of a breast cancer mammography screening program in Southern Brazil. A trained investigator administered a standardized interview to collect sociodemographic and clinical data, and body weight history (weight at menarche, at marriage, at first and last pregnancy, and at menopause). Current anthropometric measurements were also made. Fifty-seven women with cancer (66.7% postmenopausal) and 159 controls were included. Current age (60.3 ± 10.4 vs. 55.8 ± 8.4 years, P weight at different stages of life. Women with social vulnerability recruited at a mammography screening program in Southern Brazil showed a large weight gain during life, but no significant differences were found in body weight between women with or without breast cancer.

    Full Text Available The role of passive smoking on breast cancer risk was unclear. This study aimed to evaluate the association between passive smoking and breast cancer risk among Chinese women.A hospital-based case-control study, including 877 breast cancer cases and 890 controls, frequency-matched by age and residence, was conducted. A structured questionnaire was used to collect information on passive smoking history through face-to-face interview by trained interviewers. Unconditional logistic regression models were used to estimate the association between passive smoking and breast cancer risk. A positive association between any passive smoking exposure and breast cancer risk was observed. Compared with women who were never exposed to passive smoking, women who were ever exposed had a higher breast cancer risk, with the adjusted odds ratio (OR and 95% confidence interval (CI of 1.35 (1.11-1.65. Similar result was found on home passive smoking exposure and breast cancer risk, but not on workplace passive smoking exposure. Women who were ever exposed to tobacco smoke at home had a higher risk of breast cancer compared with never exposed women, with the adjusted OR (95% CI of 1.30 (1.05-1.61. Home passive smoking exposure showed significant dose-response relationships with breast cancer risk in smoker-years, cigarettes/day and total pack-years (Ptrend=0.003, 0.006 and 0.009, respectively. An increased total smoker-years of any passive exposure significantly elevated the risk of breast cancer (Ptrend<0.001. Positive associations and dose-response relationships were found among postmenopausal women and all subtypes of estrogen receptor (ER and progesterone receptor (PR status of breast cancer.Passive smoking was associated with an increased risk of breast cancer among non-smoking Chinese women. A stronger positive association with breast cancer risk was seen mainly among postmenopausal women.

    Full Text Available Invasive apocrine carcinomas of the breast are rare. Fine needle aspiration cytology (FNAC has been increasingly used as a primary screening tool for breast lumps, with high level of sensitivity and specificity. Preoperatively, apocrine carcinoma needs to be distinguished from benign apocrine lesions and other eosinophilic and granular cell tumors. We report a rare case of invasive apocrine carcinoma in a 70-year-old female presenting with a breast lump and no axillary lymphadenopathy. FNAC was advised which yielded moderately cellular smears composed of loosely cohesive clusters of large, polygonal cells with centrally located pleomorphic, vesicular nucleus with prominent nucleoli and abundant, basophilic and granular cytoplasm. Based on above cytomorphological findings, diagnosis of apocrine carcinoma was offered. The patient then underwent right modified radical mastectomy with axillary clearance. Based on histomorphology and panel of immunohistochemical (IHC markers the diagnosis was confirmed. Although apocrine/oncocytic cytomorphology is seen in few types of breast neoplasms, high index of suspicion and subsequent IHC study clinches the diagnosis.

    Full text: There are many incidences in Nuclear Medicine where incidental findings of pathologies other than those under investigation are found. This is mainly due to the non-specific biodistribution of the radiopharmaceuticals throughout the body. Sestamibi is one such agent that can be used for multi-imaging purposes, such as cardiac, parathyroid and carcinoma imaging. A female patient with a known history of cardiac disease presented to our department for a myocardial perfusion stress rest study. Dipryridamole was used instead of an exercise test due to leg pain and poor patient mobility. 450MBq of 99mTc- Sestamibi was injected into the patient during stress and a further IOOOMBq of 99mTc-Sestamibi during rest approximately three hours later. Post stress/rest images illustrated not only a small inferolateral infarct, but also an abnormal focus of increased activity in the right breast in the lower outer quadrant. Knowing 99mTc-Sestamibi to have a high affinity to carcinoma cells, the abnormal focal uptake was correctly diagnosed as a breast cancer malignancy. Breast cancer was confirmed on mammography and the patient underwent breast surgery, chemotherapy and radiation therapy. This case highlights the importance of thoroughly checking all cardiac SPECT 99mTc-Sestamibi cine images for incidental findings of other pathologies.

    Full Text Available A case – control study of 257 women with breast cancer and 565 control women was conducted to investigate the effect of life-time sport activity on breast cancer risk. Information was collected by questionnaire about sports played, frequency of participation and duration. The activity levels were determined using frequency variable weighted for metabolic equivalents of energy expenditure (MET. Multivariate logistic regression analyses were used to compute odds ratios (ORs and 95% confidence intervals (CIs. A full assessment of confounding and effect modification was undertaken. The odds ratios for increasing tertiles of sport activity were 1.00 (referent, 0.50 (CI: 0.33-0.76 and 0.44 (CI: 0.28-0.64, respectively (P-trend = 0.000. Comparing sport active women to inactive women the OR was 0.49 (CI: 0.35-0.69. Models stratified according to body mass index, age at menarche, age at first full term pregnancy, intake of vegetables and fruits, and experience of stress were examined. In models stratified the risks of breast cancer were also reduced with higher levels of activity in sport. The conclusion is that women who participated in sports have a reduced risk of breast cancer.

    Mucinous carcinoma (also known as colloid carcinoma) is a particular type of breast cancer characterized by the presence of extracellular mucin and is linked with a more favorable prognosis than invasive breast carcinoma of no special type. Mucinous carcinoma of the breast is an uncommon form of breast tumor, often presenting as a lobulated, moderately well circumscribed mass on mammography, sonography, and MRI imaging. It accounts for 1 to 7% of all breast cancers. Pure mucinous breast carcinomas are rare and account for about 2% of all primary breast carcinomas. Metastatic disease happens at a lower rate than in other types of invasive carcinoma. We present our 5 year experience with this particular pathology in a retrospective review study. We identified 25 patients with mixed and pure mucinous breast cancer, the tumor size varied greatly from 2 to 19 cm in diameter. A subset of mixed mucinous carcinomas (8 cases) showed neuroendocrine differentiation or other associated premalignant lessions. Mucinous carcinoma of the breast is a rare entity with a favorable prognosis due to low incidence of lymph node metastases. Pure mucinous breast carcinoma has an even rare.

    A case-control study was undertaken to investigate the role of diet in women with breast cancer, and in two groups of women with benign breast disease: epithelial hyperplasia, and fibrocystic disease without hyperplasia. The study provides data which suggest that the consumption of red meat, savoury meals (pizza, pies, stew, etc.) and of starches is disadvantageous, while the consumption of chicken and fish, and of fruit, appears to be beneficial. These patterns were present for both the breast cancer patients and the patients with benign epithelial hyperplasia. One-third of breast cancer patients had changed their diet after their diagnosis, compared to only around 12% in controls and patients with benign breast disease. Overall, the women studied had changed their diet to reduce their intake of sugars, dairy products and meat, and increased their intake of poultry, fish, fruit and vegetables over the past decade; but the breast cancer group was less likely to have made this change.

    Full Text Available Abstract Introduction Breast cancer is one of the most important health problems in the world and affects a great number of women over the entire globe. This group of tumors rarely presents as bilateral disease and, when it does happen, normally occurs within the same histological type. We report a rare case of concurrent bilateral breast cancer with two different histology types, a breast carcinoma and a breast sarcoma, in a 42-year-old woman referred to our hospital. Case presentation A 42-year-old Caucasian woman admitted to our institute in August 1999, presented with a nodule in the left breast of 3.0 × 2.5 cm, and, in the right breast, one of 1.0 cm, suspected of malignancy and with a clinically negative armpit. Biopsies had revealed invasive mammary carcinoma (right breast and sarcoma (left breast. She was submitted to bilateral modified radical mastectomy. A histological study showed an invasive mammary carcinoma degree II lobular pleomorphic type with invasion of seven of the 19 excised axillary nodes in the right breast and, in the left breast, a sarcoma of the mammary stroma, for which the immunohistochemistry study was negative for epithelial biomarkers and positive for vimentin. Later, she was submitted for chemotherapy (six cycles of 75 mg/m2 5-fluorouracil, epirubicin and cyclophosphamide followed by radiotherapy of the thoracic wall and axillary nodes on the left. Hormone receptors were positive in the tumor of the right breast, and tamoxifen, 20 mg, was prescribed on a daily basis (five years followed by letrozole, 2.5 mg, also daily (five years. She presented no sign of negative evolution in the last consultation. Conclusion The risk of development of bilateral breast cancer is about 1% each year within a similar histological type, but it is higher in tumors with lobular histology. In this case, the patient presented, simultaneously, two histologically distinct tumors, thus evidencing a rare situation.

    In a previous paper, we had assumed that the risk of screen-detected breast cancer mostly reflects inherent risk, and the risk of whether a breast cancer is interval versus screen-detected mostly reflects risk of masking. We found that inherent risk was predicted by body mass index (BMI) and dense area (DA) or percent dense area (PDA), but not by non-dense area (NDA). Masking, however, was best predicted by PDA but not BMI. In this study, we aimed to investigate if these associations vary by tumor characteristics and mode of detection. We conducted a case-control study nested within the Melbourne Collaborative Cohort Study of 244 screen-detected cases matched to 700 controls and 148 interval cases matched to 446 controls. DA, NDA and PDA were measured using the Cumulus software. Tumor characteristics included size, grade, lymph node involvement, and ER, PR, and HER2 status. Conditional and unconditional logistic regression were applied as appropriate to estimate the Odds per Adjusted Standard Deviation (OPERA) adjusted for age and BMI, allowing the association with BMI to be a function of age at diagnosis. For screen-detected cancer, both DA and PDA were associated to an increased risk of tumors of large size (OPERA ~ 1.6) and positive lymph node involvement (OPERA ~ 1.8); no association was observed for BMI and NDA. For risk of interval versus screen-detected breast cancer, the association with risk for any of the three mammographic measures did not vary by tumor characteristics; an association was observed for BMI for positive lymph nodes (OPERA ~ 0.6). No associations were observed for tumor grade and ER, PR and HER2 status of tumor. Both DA and PDA were predictors of inherent risk of larger breast tumors and positive nodal status, whereas for each of the three mammographic density measures the association with risk of masking did not vary by tumor characteristics. This might raise the hypothesis that the risk of breast tumours with poorer prognosis

    Inducible costimulator (ICOS), a costimulatory molecular of the CD28 family, provides positive signal to enhance T cell proliferation. Its abnormal expression can disturb the immune response and entail an increased risk of cancer. To investigate whether single nucleotide polymorphisms (SNPs) in the ICOS gene are associated with sporadic breast cancer susceptibility and progression in Chinese women, a case-control study was conducted. In the study cohort, we genotyped five SNPs (rs11889031, rs10932029, rs4675374, rs10183087 and rs10932037) in ICOS gene among 609 breast cancer patients and 665 age-matched healthy controls. Furthermore, the positive results were replicated in an independent validation cohort of 619 patients and 682 age-matched healthy controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the genotypes. In rs10932029, compared with TT genotype and T allele, the CT genotype and C allele showed a significantly increased risk of breast cancer (P = 0.030, OR = 1.467, 95% CI 1.037-2.077; P = 0.017, OR = 1.481, 95% CI 1.070-2.049, respectively), and the associations were also significant in the validation cohort (P = 0.002, OR = 1.693, 95% CI 1.211-2.357; P = 0.003, OR = 1.607, 95% CI 1.171-2.204, respectively). Haplotype analysis showed that CTCAC haplotype containing rs10932029 T allele had a lower frequency in cases than in controls (P = 0.015), whereas haplotype CCCAC containing rs10932029 C allele was more common in cases than in controls (P = 0.013). In the analysis of clinicopathologic features, rs11889031 CT genotype and T allele were associated with progesterone receptor (PR) status and lymph node metastasis, which were further supported by our validation cohort. Moreover, some haplotypes were associated with estrogen receptor (ER) and PR statuses. These results indicate that ICOS gene polymorphisms may affect the risk of breast cancer and show that some SNPs are associated with breast cancer

    Full Text Available Over the last three decades an increase in the incidence of breast cancer has been observed in the previously low-risk Asian countries. This study is designed to determine the risk factors of breast cancer for Pakistani women as little information exists in this regard. A case-control study of 564 female breast cancer cases diagnosed at the two cancer hospitals at Lahore (INMOL and SKMCH during the time period Jan 1, 1998 to Dec 31, 1998 was carried out. Four hundred and forty eight women aged 24-80 years out of 564 cases were complete with respect to defined criteria and were eligible for the study. Population-based controls were selected to match for age of cases in the ratio 1:2. The data were analyzed considering ‘all women’ and then separate analyses were done for ‘premenopausal’ and ‘postmenopausal women’. Women with family history of breast cancer, history of consanguineous marriage, smoking and high BMI (≥28 are at increased risk of breast cancer for all three groups. Early menarche (45 years was a strong determinant of breast cancer. Higher number of full-term pregnancies (>3 was protective for ‘all women’ and ‘premenopausal women’ but in case of ‘postmenopausal women’ the poor with higher number of pregnancies were significantly protected. Late age at first FTP (>25 years is a significant risk factor for postmenopausal women.

    Catechol-O-methyltransferase (COMT) inactivates catechol estrogens by methylation and thus may play a protective role against mutations induced by estrogen metabolites. In this study we investigated the relationship between the Vall58Met polymorphism in the COMT gene and breast cancer risk in a population-based case control study in Syria. We examined 135 breast cancer patients and 107 healthy controls in North Syria to determine the association between the functional genetic Val158Met polymorphism in the COMT gene and female breast cancer risk. There was no significant overall association between the COMT genotype and individual susceptibility to breast cancer. Our data suggest that there may be no overall association between the COMT genotype and breast cancer.

    Ongoing breast cancer screening programs can only be evaluated using observational study designs. Most studies have observed a reduction in breast cancer mortality, but design differences appear to have resulted in different estimates. Direct comparison of case-control and trial analyses gives more insight into this variation. Here, we performed case-control analyses within the randomized UK Age Trial. The Age Trial assessed the effect of screening on breast cancer mortality in women ages 40-49 years. In our approach, case subjects were defined as breast cancer deaths between trial entry (1991-1997) and 2004. Women were ages 39-41 years at entry. For every case subject, five control subjects were selected. All case subjects were included in analyses of screening invitation (356 case subjects, 1,780 controls), whereas analyses of attendance were restricted to women invited to screening (105 case subjects, 525 age-matched controls). Odds ratios (OR) were estimated with conditional logistic regression. We used and compared two methods to correct for self-selection bias. Screening invitation resulted in a breast cancer mortality reduction of 17% (95% confidence interval [CI]: -36%, +6%), similar to trial results. Different exposure definitions and self-selection adjustments influenced the observed breast cancer mortality reduction. Depending on the method, "ever screened" appeared to be associated with a small reduction (OR: 0.86, 95% CI: 0.40, 1.89) or no reduction (OR: 1.02, 95% CI: 0.48, 2.14) using the two methods of correction. Recent attendance resulted in an adjusted mortality reduction of 36% (95% CI: -69%, +31%) or 45% (95% CI: -71%, +5%). Observational studies, and particularly case-control studies, are an important monitoring tool for breast cancer screening programs. The focus should be on diminishing bias in observational studies and gaining a better understanding of the influence of study design on estimates of mortality reduction.

    To characterise the relationship between breast cancer and different aspects of the reproductive life, use of drugs and alcohol by family history of breast cancer. From the cancer registry of Girona, Spain, 330 women were identified with histologically confirmed breast cancer during 1986-1989. For each case, a control woman was selected from a random sample of the population living in the matched area to the case by age (+/- 5 yr.). The information was collected by a personal interview and included: family history of breast cancer, reproductive history, presence of acne during the teenage years, use of oral contraceptives and drugs for sleep and anxiety disorders, and alcohol consumption. 18.5% of breast cancer cases and 8.9% of all controls had a family history of breast cancer. Family history on a first degree relative (mother or sister) was present in 10.6% of the cases and 2.8% of controls, which represented an odds ratio for breast cancer of 3.7 (95% CI, 1.8-7.8) higher than the general population. Women with a first degree family history of breast cancer were at higher risk for breast cancer if they had a history of acne during the teenage period (OR = 2.4; 95% CI, 1.1-5.2) and if they referred long menstrual periods in the early years of menarche (OR = 3.1; 95% CI, 1.3-7.0). Women with no family history had a higher breast cancer risk if they had a late menarche, long menstrual periods, late first full term pregnancy, and history of acne during puberty. Alcohol consumption and use of drugs for anxiety and sleep disorders were associated with a decreased risk of breast cancer. First degree family history of breast cancer seems to be the best risk indicator for developing breast cancer. Long menstrual periods and presence of acne during puberty may indicate hormonal imbalance that act independently of the family history in breast cancer development.

    Full Text Available Breast cancer is the most common cancer in women worldwide. In the Moroccan context, the role of well-known reproductive factors in breast cancer remains poorly documented. The aim of this study was to explore the relationship between menstrual and reproductive factors and breast cancer risk in Moroccan women in the Fez region.A case-control study was conducted at the Hassan II University Hospital of Fez between January 2014 and April 2015. A total of 237 cases of breast cancer and 237 age-matched controls were included. Information on sociodemographic characteristics, menstrual and reproductive history, family history of breast cancer, and lifestyle factors was obtained through a structured questionnaire. Conditional logistic regression models were used to estimate odds ratios and 95% confidence intervals for breast cancer by menstrual and reproductive factors adjusted for potential confounders.Early menarche (OR = 1.60, 95% CI: 1.08-2.38 and nulliparity (OR = 3.77, 95% CI: 1.98-7.30 were significantly related to an increased risk of breast cancer, whereas an early age at first full-term pregnancy was associated with a decreased risk of breast cancer (OR = 0.41, 95% CI: 0.25-0.65.The results of this study confirm the role of established reproductive factors for breast cancer in Moroccan women. It identified some susceptible groups at high risk of breast cancer. Preventive interventions and screening should focus on these groups as a priority. These results should be confirmed in a larger, multicenter study.

    Mammography screening reduces breast cancer mortality by up to 32%. However, some recent studies have questioned the impact of non-palpable breast cancer detection on mortality reduction. The aim of this study was to analyse the clinicopathological and long-term follow-up data of early stage screened and symptomatic breast cancer patients. The institutional prospectively led database was systematically analysed for breast cancer cases diagnosed via the mammography screening program from 2002 to 2009. As a control group, symptomatic early stage breast cancer patients were collected randomly from the same database and matched for age and follow-up period. All medical records were reviewed retrospectively. Data from 298 breast cancer patients were collected from 47,718 mammography screenings. In addition, 331 symptomatic breast cancer patients were randomly selected. The screened group presented a significantly lower median tumour size (P screened group (P screened group did not exhibit better overall (P = 0.717) or disease-free survival (P = 0.081) compared to the symptomatic group. Our results do not suggest that mammography screening does not reduce breast cancer mortality but the mammography screening did not bring any significant improvement in patient overall or disease-free survival for the early stage breast cancer patients compared to the symptomatic group. The drawback of symptomatic early stage tumours compared to non-palpable tumours could be equalized by modern multimodality oncology treatments.

    A number of studies have evidenced the effect of modifiable lifestyle factors such as diet, breastfeeding and nutritional status on breast cancer risk. However, none have addressed the missing data problem in nutritional epidemiologic research in South America. Missing data is a frequent problem in breast cancer studies and epidemiological settings in general. Estimates of effect obtained from these studies may be biased, if no appropriate method for handling missing data is applied. We performed Multiple Imputation for missing values on covariates in a breast cancer case-control study of Córdoba (Argentina) to optimize risk estimates. Data was obtained from a breast cancer case control study from 2008 to 2015 (318 cases, 526 controls). Complete case analysis and multiple imputation using chained equations were the methods applied to estimate the effects of a Traditional dietary pattern and other recognized factors associated with breast cancer. Physical activity and socioeconomic status were imputed. Logistic regression models were performed. When complete case analysis was performed only 31% of women were considered. Although a positive association of Traditional dietary pattern and breast cancer was observed from both approaches (complete case analysis OR=1.3, 95%CI=1.0-1.7; multiple imputation OR=1.4, 95%CI=1.2-1.7), effects of other covariates, like BMI and breastfeeding, were only identified when multiple imputation was considered. A Traditional dietary pattern, BMI and breastfeeding are associated with the occurrence of breast cancer in this Argentinean population when multiple imputation is appropriately performed. Multiple Imputation is suggested in Latin America’s epidemiologic studies to optimize effect estimates in the future. PMID:27892664

    Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

    Full Text Available Abstract Background Pesticides are widely used in households to control insects and weeds. Several studies, over the past decades, have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We, therefore, present a case-control study examining self-reported exposure to household pesticides with regard to associated risk of breast cancer. Methods This study was conducted in the area in and around New York City, NY and included 1205 patients (447 cases and 758 controls. Cases were defined as women with newly diagnosed breast cancer or carcinoma in-situ, while controls included women with benign breast diseases or those undergoing non-breast related surgery. All patients were asked a series of questions to determine their pesticide exposure, including the type of pesticide, location of exposure (inside vs. outside the home, who applied the pesticide (self vs. a professional and duration of pesticide use. Logistic regression models were used to estimate unadjusted and adjusted odds ratios (OR and corresponding 95% confidence intervals (CI. Results The most common pests encountered in participants' homes were ants, carpenter ants, and cockroaches. The calculated adjusted odds ratios for both self and professionally applied pesticides, specifically against the above mentioned insects, with regard to breast cancer risk were 1.25 (95% CI: 0.79-1.98 and 1.06 (95% CI: 0.65-1.73, respectively. Similarly, odds ratios and confidence intervals were calculated for other types of pesticides. Conclusions Overall, the results of our study did not show an association between self-reported exposure to pesticides and breast cancer risk. Future studies, utilizing a larger sample size and more specific detail on time frame of pesticide exposure, are needed to

    This study aims to examine the association of breast cancer with dietary patterns among Chinese women. A population-based case-control study was conducted in Jiangsu, China. Newly diagnosed primary breast cancer patients were recruited as cases (n = 818). Controls (n = 935), selected from the general population, were frequency matched to cases. A validated food frequency questionnaire was used to assess dietary intake. Dietary patterns were identified by factor analysis and multivariable odds ratios (OR) and 95% confidence intervals (CI) were estimated. Four dietary patterns were identified: salty, vegetarian, sweet and traditional Chinese. The traditional Chinese pattern was found to be robustly associated with a lower risk of breast cancer among both pre- and post-menopausal women (4th vs. 1st quartile: OR for pre- and post-menopausal women was 0.47 and 0.68, respectively). Women with high factor scores of the sweet pattern also showed a decreased risk of breast cancer (4th vs. 1st quartile: OR for pre- and post-menopausal women was 0.47 and 0.68, respectively). No marked association was observed between a vegetarian pattern or a salty pattern and breast cancer. These findings indicate that dietary patterns of the traditional Chinese and the sweet may favorably associate with the risk of breast cancer among Chinese women.

    Previous research has not been conclusive regarding the association between selenium (Se) and breast cancer. This study was conducted to clarify if there is an association between prediagnostic serum Se levels and breast cancer risk. A population based cohort, the Malmö Diet and Cancer Study, was used and linked with the Swedish cancer registry up to 31 December 2013. Our study included 1,186 women with breast cancer and an equal number of controls. Selenium levels were analysed from stored serum samples. The included individuals were divided into quartiles based on Se value and we compared breast cancer cases with controls using logistic regression yielding odds ratios (OR) with 95% confidence intervals. Serum Se was also analysed as a continuous variable regarding breast cancer risk. The analyses were adjusted for established risk factors and stratified on smoking status and body mass index (BMI). When comparing the highest Se quartile with the lowest, the adjusted OR for breast cancer was 0.98 (0.75-1.26). With selenium as a continuous variable the adjusted OR was 1.00 (1.00-1.01) per 10 ng/ml. When comparing the highest with the lowest Se quartile in women with BMI > 25 kg/m 2 the adjusted OR was 0.77 (0.53-1.14). We conclude that it is unlikely that prediagnostic serum selenium is overall associated with breast cancer risk and no modifying effect from BMI or smoking was seen. © 2017 UICC.

    Some previous studies have suggested that exposure to engine exhausts may increase risk of breast cancer. In a population-based case-control study of breast cancer in Western Australia we assessed occupational exposure to engine exhausts using questionnaires and telephone interviews. Odds Ratios (OR) and 95% Confidence Intervals (CI) were calculated using logistic regression. We found no association between risk of breast cancer and occupational exposure to diesel exhaust (OR 1.07, 95%CI: 0.81-1.41), gasoline exhaust (OR 0.98, 95%CI: 0.74-1.28), or other exhausts (OR 1.08, 95%CI: 0.29-4.08). There were also no significant dose- or duration-response relationships. This study did not find evidence supporting the association between occupational exposures to engine exhausts and breast cancer risk. Am. J. Ind.

    In 1972, Beck introduced an inventory (BDI) for rapid screening of depression. The associations between the BDI and the risk of breast cancer (BC) are rarely considered together in prospective studies. In an extension of the Kuopio Breast Cancer Study, 115 women with breast cancer symptoms were semi-structurally interviewed in-depth as well as asked to complete standardised questionnaires (Forsen, Spielberger, MADRS), and all study variables were obtained before any diagnostic procedures were carried out. BDI was used to evaluate the depression of the study participants. The clinical examinations and biopsies showed BC in 34 patients, benign breast disease (BBD) in 53 patients, and 28 individuals were shown to be healthy (HSS). There was a trend for the women with HSS to have less sadness (BDI mean score, 0.27) than those of the BC (BDI mean score, 0.56) and BBD groups (BDI mean score, 0.49). The HSS group tended to be less pessimistic (BDI mean score, 0.15) than the patients in the BC group (BDI mean score, 0.44) and in the BBD group (BDI mean score, 0.42). The HSS group also had less self-accusation (BDI mean score, 0.19) than the patients in the BC group (BDI mean score, 0.50) and the patients in the BBD group (BDI mean score, 0.62). The HSS group also reported less work inhibition and weight loss than the patients in the BC group and in the BBD group. The mean sum of the scores of BDI variables was significantly lower in the HSS group (BDI mean score, 7.1) than in the BC (BDI mean score, 8.4) or BBD groups (BDI mean score, 8.8). The results of this study do not support a specific link between BDI and breast cancer risk. However, the patients with BC and BBD tended to have an increased risk for depressive symptoms.

    Epidemiologic and animal data indicate that night shift work might increase the risk for breast cancer. We evaluated the association of night work with different clinical types of breast cancer in a population based case-control study (MCC-Spain study) taking into account chronotype, an individual characteristic that may relate to night shift work adaptation. Lifetime occupational history was assessed by face-to-face interviews and shift work information was available for 1708 breast cancer cases and 1778 population controls from 10 Spanish regions, enrolled from 2008 to 2013. We evaluated three shift work domains, including shift work type (permanent vs rotating), lifetime cumulative duration and frequency. We estimated odds ratios (OR) for night work compared to day work using unconditional logistic regression models adjusting for confounders. Having ever worked permanent or rotating night shift was associated with an increased risk for breast cancer compared to day workers [odds ratio (OR) 1.18; 95 % CI 0.97, 1.43]. Chronotype was differentially associated with breast cancer depending on the duration of night shift work. Risk was higher in women with invasive tumors (OR 1.23; 95 % CI 1.00, 1.51) and for estrogen and progestagen positive tumors among premenopausal women (OR 1.44; 95 % CI 1.05, 1.99). Having ever performed night shift was associated with a small increased risk for breast cancer and especially in subgroups of women with particular hormone related characteristics.

    Breast cancer is one of the most common cancers of women in India with high fatality rate. Over a 1 year study period 105 consecutive biopsy or fine needle aspiration cytology confirmed breast cancer patients were interviewed by direct questionnaire method regarding risk factors attending Surgery and Radiotherapy OPD of Medical College Kolkata, West Bengal while taking other 105 patients attending Surgery Department for some other disease as controls. The data were compiled in MS Excel 2007 and analyzed by Epi info 3.5.1 software. Among the cases, rural residence, illiteracy and low socio-economic status was significantly higher than controls. Late onset of menarche, late onset of menopause, ever OCP usage, breast feeding for 1-2 years and age of 1st childbirth between 20-30 years were found to be significant protective factors. People should be made aware regarding the modifiable risk factors to prevent breast cancer.

    Ionizing radiation and high levels of circulating estradiol are known breast cancer carcinogens. We investigated the risk of first primary postmenopausal breast cancer in relation to the combined effects of whole-body ionizing radiation exposure and prediagnostic levels of postmenopausal sex hormones, particularly bioavailable estradiol (bE 2 ). A nested case-control study of 57 incident breast cancer cases matched with 110 controls among atomic bomb survivors. Joint effects of breast radiation dose and circulating levels of sex hormones were assessed using binary regression and path analysis. Radiation exposure, higher levels of bE 2 , testosterone and progesterone, and established reproductive risk factors were positively associated with postmenopausal breast cancer risk. A test for mediation of the effect of radiation via bE 2 level suggested a small (14%) but significant mediation (p = 0.004). The estimated interaction between radiation and bE 2 was large but not significant (interaction = 3.86; p = 0.32). There is accumulating evidence that ionizing radiation not only damages DNA but also alters other organ systems. While caution is needed, some portion of the radiation risk of postmenopausal breast cancer appeared to be mediated through bE 2 levels, which may be evidence for cancer risks due to both direct and indirect effects of radiation.

    Fine needle aspiration cytology (FNAC) is a simple, rapid, inexpensive, and reliable method of diagnosis of breast mass. Cytoprognostic grading in breast cancers is important to identify high-grade tumors. Computer-assisted image morphometric analysis has been developed to quantitate as well as standardize various grading systems. To apply nuclear morphometry on cytological aspirates of breast cancer and evaluate its correlation with cytomorphological grading with derivation of suitable cutoff values between various grades. Descriptive cross-sectional hospital-based study. This study included 64 breast cancer cases (29 of grade 1, 22 of grade 2, and 13 of grade 3). Image analysis was performed on Papanicolaou stained FNAC slides by NIS -Elements Advanced Research software (Ver 4.00). Nuclear morphometric parameters analyzed included 5 nuclear size, 2 shape, 4 texture, and 2 density parameters. Nuclear size parameters showed an increase in values with increasing cytological grades of carcinoma. Nuclear shape parameters were not found to be significantly different between the three grades. Among nuclear texture parameters, sum intensity, and sum brightness were found to be different between the three grades. Nuclear morphometry can be applied to augment the cytology grading of breast cancer and thus help in classifying patients into low and high-risk groups.

    Full Text Available CONTEXT AND OBJECTIVE: Previous studies have suggested that the occurrence of pregnancy concomitantly with a diagnosis of breast cancer may affect the evolution of the neoplasia. The present study aimed to compare pregnancy-associated breast cancer (PABC patients with non-pregnant cancer patients (controls in relation to the time taken to diagnose the disease, tumor characteristics and mortality. DESIGN AND SETTING: A retrospective, paired case-control study was conducted at the Hospital da Santa Casa de Misericórdia and Centro de Quimioterapia Antiblástica e Imunoterapia in Belo Horizonte, Brazil. METHODS: The study involved 87 PABC and 252 control patients. The influence of covariables (interval between first symptoms and diagnosis, tumor histology, size of primary tumor, distant metastasis, grade of malignancy, hormone receptor status and axillary lymph node involvement and the pregnancy variable on overall survival was investigated using univariate and multivariate analyses. RESULTS: The median overall survival for PABC patients of 30.1 months (95% confidence interval, CI: 19.4-40.9 months was significantly different (P = 0.005 from that of the control group (53.1 months; 95% CI: 35.1-71.0 months. The cumulative overall survivals after five and ten years were, respectively, 29.7 and 19.2% for PABC patients, and 47.3 and 34.8% for control patients (P = 0.005. Tumor size, grade of malignancy, distant metastasis and pregnancy were independent factors that significantly modified disease prognosis. CONCLUSIONS: Pregnancy was an independent prognostic factor. The overall survival of PABC patients was shorter than that of non-pregnant patients.

    Risk of breast cancer is increased in women with proliferative benign breast conditions. Most of these conditions, however, do not progress to breast cancer. The purpose of our study was to identify factors possibly associated with this progression. Women with proliferative fibrocystic breast conditions alone (214), and women with proliferative fibrocystic breast conditions and concurrent breast cancer (130), were compared to each other, and each of these groups of women were also compared to 1,070 controls; and 176 women with non-proliferative benign breast conditions alone, and 155 also with breast cancer, were similarly compared. All study subjects were selected from a cohort of women enrolled in a trial of breast self-examination in Shanghai. Women were interviewed to ascertain information on suspected risk factors for breast cancer and dietary habits. Conditional logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Increased risks of both proliferative fibrocystic breast conditions alone, and with breast cancer, were associated with low parity, a prior benign breast lump and breast cancer in a first-degree relative. Decreasing trends in the risk of both conditions with increasing intake of fruits and vegetables were observed. No factors were significantly associated with risk of breast cancer relative to risk of proliferative changes. Similar, but in some instances weaker, associations were observed for non-proliferative fibrocystic conditions with and without breast cancer. The possible risk or protective factors that were observed in our study most likely alter the risk of breast cancer at an early stage in the carcinogenic process, and probably do not alter risk of progression from proliferative fibrocystic breast conditions to breast cancer.

    Environmental Persistent Organic Pollutants (POPs) can alter the hormone homeostasis by mimicking, interfering or blocking the function of hormones; moreover POPs are hypothesized to modify the risk of breast cancer. The association between POPs and breast cancer has been widely studied but the conclusions are inconsistent. The present study examined the associations between serum levels of POPs and breast cancer with focus on the highly exposed Greenlandic Inuit population. The study design was a case-control study of Inuit women from Greenland. The participants were asked to complete a questionnaire with information on reproductive history and lifestyle and to provide a blood sample. The sampling was carried out in two time periods (2000-2003 and 2011-2014). The serum levels were determined of 14 polychlorinated biphenyls (PCBs), 11 organochlorine pesticides (OCPs), 16 perfluoroalkyl acids (PFAAs), 1 polybrominated biphenyl (PBB), and 9 polybrominated diphenyl ethers (PBDEs). Independent samples t-test was used to compare differences between cases and controls and odds ratios (OR) adjusted for identified confounders were obtained using logistic regression. The study population included 77 breast cancer cases and 84 controls. The majority of the measured compounds declined significantly from 2000 - 2003 to 2011-2014. However, for the perfluorinated carboxylic acids (PFCAs) an increase was observed. The serum levels were significantly higher in cases compared to controls for the majority of the compounds, and after adjusting for age the difference was maintained for ∑OCP, dichlorodiphenyldichloroethylene (p,p'-DDE), ∑PFAA, ∑perfluorinated sulfonic acids (PFSA), perfluorohexane sulfonate (PFHxS), and perfluorooctane sulfonate (PFOS). For the lipophilic POPs, high serum levels (middel/highest vs. lowest tertile) of ∑PCB, ∑estrgoenicPCB, PCB99, PCB138, PCB153, PCB170, PCB170, and PCB183 was associated with breast cancer risk; for the amphiphilic PFAAs, high

    Interleukins and cytokines play an important role in the pathogenesis of many solid cancers. Several single nucleotide polymorphisms (SNPs) identified in cytokine genes are thought to influence the expression or function of these proteins and many have been evaluated for their role in inflammatory disease and cancer predisposition. The aim of this study was to evaluate any role of specific SNPs in the interleukin genes IL1A, IL1B, IL1RN, IL4R, IL6 and IL10 in predisposition to breast cancer susceptibility and severity. Candidate single nucleotide polymorphisms (SNPs) in key cytokine genes were genotyped in breast cancer patients and in appropriate healthy volunteers who were similar in age, race and sex. Genotyping was performed using a high throughput allelic discrimination method. Data on clinico-pathological details and survival were collected. A systematic review of Medline English literature was done to retrieve previous studies of these polymorphisms in breast cancer. None of the polymorphisms studied showed any overall predisposition to breast cancer susceptibility, severity or to time to death or occurrence of distant metastases. The results of the systematic review are summarised. Polymorphisms within key interleukin genes (IL1A, IL1B, IL1RN, IL4R, IL6 and IL10 do not appear to play a significant overall role in breast cancer susceptibility or severity

    Leptin, a 16 kDa polypeptide hormone, implicated in various physiological processes, exerts its action through the leptin receptor, a member of the class I cytokine receptor family. Both leptin and leptin receptor have recently been implicated in processes leading to breast cancer initiation and progression in animal models and humans. An A to G transition mutation in codon 223 in exon 6 of the leptin receptor gene, resulting in glutamine to arginine substitution (Gln223Arg), lies within the first of two putative leptin-binding regions and may be associated with impaired signaling capacity of the leptin receptor. This study was designed to assess the role of this polymorphism in breast cancer susceptibility in Nigerian women. We utilized a polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) assay to evaluate the association between the Gln223Arg polymorphism of the leptin receptor gene and breast risk in Nigeria in a case control study involving 209 women with breast cancer and 209 controls without the disease. Study participants were recruited from surgical outpatient clinics and surgical wards of four University Teaching Hospitals located in Midwestern and southeastern Nigeria between September 2002 and April 2004. Premenopausal women carrying at least one LEPR 223Arg allele were at a modestly increased risk of breast cancer after adjusting for confounders (OR = 1.8, 95% confidence interval [CI] 1.0–3.2, p = 0.07). There was no association with postmenopausal breast cancer risk (OR = 0.9, 95% CI 0.4–1.8, p = 0.68). Our results suggest that the LEPR Gln223Arg polymorphism in the extracellular domain of the LEPR receptor gene is associated with a modestly increased risk of premenopausal breast cancer in Nigerian women

    Several epidemiologic studies have reported a positive association between breast cancer risk and high intake of sweets, which may be due to an insulin-related mechanism. We investigated this association in a population-based case-control study of 1,434 cases and 1,440 controls from Long Island, NY. Shortly after diagnosis, subjects were interviewed in-person to assess potential breast cancer risk factors, and self-completed a modified Block food frequency questionnaire, which included 11 items pertaining to consumption of sweets (sweet beverages, added sugars, and various desserts) in the previous year. Using unconditional logistic regression models, we estimated the association between consumption of sweets and breast cancer. Consumption of a food grouping that included dessert foods, sweet beverages, and added sugars was positively associated with breast cancer risk [adjusted odds ratio (OR) comparing the highest to the lowest quartile: 1.27, 95% confidence interval (CI): 1.00-1.61]. The OR was slightly higher when only dessert foods were considered (OR: 1.55, 95% CI: 1.23-1.96). The association with desserts was stronger among pre-menopausal women (OR: 2.00, 95% CI: 1.32-3.04) than post-menopausal women (OR: 1.40, 95% CI: 1.07-1.83), although the interaction with menopause was not statistically significant. Our study indicates that frequent consumption of sweets, particularly desserts, may be associated with an increased risk of breast cancer. These results are consistent with other studies that implicate insulin-related factors in breast carcinogenesis.

    Certain features of pregnancy are important risk factors for breast cancer, such as protection afforded by young age at first birth. Preeclampsia, a pregnancy complication, is associated with reduced maternal breast cancer risk. However, questions remain regarding causality, biological mechanisms and the relation of other hypertensive conditions to risk. We conducted a population-based case-control study of breast cancer cases (n=116,196) in parous women identified through linkage of birth and cancer registries in Denmark, Finland, Norway and Sweden (1967-2013), including up to 10 matched controls per case (n=1,147,192) sampled from the birth registries (complete data were not available on all variables). Odds ratios (ORs) with 95% confidence intervals (CIs) were derived from unconditional logistic regression models including matching factors (country, maternal birth year) and parity. Hypertension diagnosed before pregnancy (OR 0.87; 95% CI 0.78-0.97), gestational hypertension (OR 0.90; 95% CI 0.86-0.93) and preeclampsia (OR 0.91; 95% CI 0.88-0.95) were associated with reduced breast cancer risk. Results remained similar after adjustment for smoking and maternal body mass index before first pregnancy, and were generally similar stratified by parity, age at breast cancer diagnosis, time since first and last birth, sex of the offspring and calendar time. Except for retained placenta (OR 1.14; 95% CI 0.98-1.32), no other pregnancy complication appeared associated with breast cancer risk. The mechanisms mediating the modest risk reductions for history of preeclampsia or hypertension preceding or arising during pregnancy, and possible increased risk with history of retained placenta are unknown and warrant further laboratory, clinical and epidemiological investigation.

    Full Text Available Breast cancer in men is a rare and infrequent disease, which occurs in a very small proportion with respect to different types of cancers. Such entity is the 0.2 to 1.5 % of all malignant tumors in men. Imaging studies have a very precise diagnostic value in these entities. It is presented the case of a male patient with apparent healthy history who comes the consultation due to palpating a "ball" in the left breast, this patient went to the Imaging Department for conducting a mammography as well performing a study with oblique craniocaudal views and a middle lateral of both nipples. Breast ultrasonography showed a nodular, homogeneous image. It was made a referral to multidiscipline breast consultation with surgical possibilities for the tumor. Due to the infrequent appearance of this entity in men, it is decided to make this case report.

    To evaluate whether hyperthyroidism or hypothyroidism increases the risk of subsequent breast cancer in an Asian population. Nationwide population-based case-control study. All healthcare facilities in Taiwan. A total of 103 466 women (mean age 53.3 years) were enrolled. 51 733 adult women with newly diagnosed primary breast cancer without a previous cancer history between 2006 and 2011 were identified and included in our study. 51 733 women with no cancer diagnosis prior to the index date were age matched as controls. Diagnosis of hyperthyroidism or hypothyroidism prior to the diagnosis of breast cancer or the same index date was identified, age, histories of thyroid disease treatment, oestrogen use and radioactive iodine treatment were adjusted. To identify risk differences in developing breast cancer among patients with a medical history of hyperthyroidism or hypothyroidism. There was a significantly increased risk of breast cancer in women with hyperthyroidism under the age of 55 years (age hypothyroidism also showed an increased risk of breast cancer (OR 1.19, P=0.029) without statistical significance after stratification by age group (age 55 years). Treatment for thyroid disorders did not alter the association in subgroup analyses (P=0.857; 0.262, respectively). Asian women under 55 years of age with history of hyperthyroidism have a significantly increased risk of breast cancer regardless of treatment. Women with history of hypothyroidism may also have an increased risk. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

    Cytokines are known as important regulators of the cancer involved in inflammatory and immunological responses. This fact and plethora of gene polymorphism data prompted us to investigate IL1 gene polymorphisms in breast cancer (BC) patients. Totally, 530 patients with BC and 628 healthy control women were studied. The genetic polymorphisms for IL1 were analyzed by Massarray Sequencing method. Three single nucleotide polymorphisms (SNPs) identified in IL1B, IL1R1 gene are thought to influence breast cancer risk. The results of the association between IL-1B, IL1R1 polymorphisms and breast cancer risk have significant. We found that the variant TT genotype of rs10490571 was associated with a significantly increased breast cancer risk (TT vs. CC: OR = 2.82, 95% CI = 1.12-7.08, P = 0.047 for the codominant model). For rs16944 (AG vs. GG: OR = 0.60, 95% CI = 0.41-0.90, P = 0.034 for the codominant model) and rs1143623 (CG vs. CC: OR = 0.65, 95% CI = 0.45-0.94, P = 0.023 for the codominant model) have significant associations were found in genetic models. In conclusion, the present analysis suggests a correlation of polymorphic markers within the IL-1 gene locus with the risk in developing breast cancer. Taken together with our finding that IL1B, IL1R1 gene three SNP are also associated with the risk for the disease, we suggest that inflammation via innate and adaptive immunity contributes to multifactorial hereditary predisposition to pathogenesis of the breast cancer.

    Growing but limited evidence suggests that night shift work is associated with breast cancer. The authors conducted a nationwide case-control study nested within a cohort of 18,551 female military employees born in 1929-1968 to investigate the risk for breast cancer after night shift work and to explore the role of leisure time sun exposure and diurnal preference. The authors documented 218 cases of breast cancer (1990-2003) and selected 899 age-matched controls from the cohort by incidence density sampling. Information on shift work, sun exposure habits, diurnal preference and other potential confounders was obtained from a structured questionnaire. ORs were estimated by multivariate conditional logistic regression. Overall, the authors observed an adjusted OR of 1.4 (95% CI 0.9 to 2.1) among women with ever compared with never night shifts. The RR for breast cancer tended to increase with increasing number of years of night shift work (p=0.03) and with cumulative number of shifts (p=0.02),with a neutral risk for fewer than three night shifts per week. The OR for the group with the highest tertile of cumulative exposure was 2.3 (95% CI 1.2 to 4.6). The most pronounced effect of night shift work on breast cancer risk was observed in women with morning chronotype preference and intense night shifts (OR=3.9, 95% CI 1.6 to 9.5). Night shift workers tended to sunbathe more frequently than day workers. The results indicate that frequent night shift work increases the risk for breast cancer and suggest a higher risk with longer duration of intense night shifts. Women with morning preference who worked on night shifts tended to have a higher risk than those with evening preference.

    Full Text Available Functional neuroimaging is an innovative but at this stage underutilized method to assess the efficacy of psychotherapy for depression. Functional magnetic resonance imaging (fMRI was used in this case study to examine changes in brain activity in a depressed breast cancer patient receiving an 8-session Behavioral Activation Treatment for Depression (BATD, based on the work of Hopko and Lejuez (2007. A music listening paradigm was used during fMRI brain scans to assess reward responsiveness at pre- and posttreatment. Following treatment, the patient exhibited attenuated depression and changes in blood oxygenation level dependence (BOLD response in regions of the prefrontal cortex and the subgenual cingulate cortex. These preliminary findings outline a novel means to assess psychotherapy efficacy and suggest that BATD elicits functional brain changes in areas implicated in the pathophysiology of depression. Further research is necessary to explore neurobiological mechanisms of change in BATD, particularly the potential mediating effects of reward responsiveness and associated brain functioning.

  17. Genetic Polymorphisms in Vitamin D Metabolism and Signaling Genes and Risk of Breast Cancer: A Nested Case-Control Study.

    Directory of Open Access Journals (Sweden)

    Tess V Clendenen

    Full Text Available Genetic polymorphisms in vitamin D metabolism and signaling genes have been inconsistently associated with risk of breast cancer, though few studies have examined SNPs in vitamin D-related genes other than the vitamin D receptor (VDR gene and particularly have not examined the association with the retinoid X receptor alpha (RXRA gene which may be a key vitamin D pathway gene. We conducted a nested case-control study of 734 cases and 1435 individually matched controls from a population-based prospective cohort study, the Northern Sweden Mammary Screening Cohort. Tag and functional SNPs were genotyped for the VDR, cytochrome p450 24A1 (CYP24A1, and RXRA genes. We also genotyped specific SNPs in four other genes related to vitamin D metabolism and signaling (GC/VDBP, CYP2R1, DHCR7, and CYP27B1. SNPs in the CYP2R1, DHCR7, and VDBP gene regions that were associated with circulating 25(OHD concentration in GWAS were also associated with plasma 25(OHD in our study (p-trend <0.005. After taking into account the false discovery rate, these SNPs were not significantly associated with breast cancer risk, nor were any of the other SNPs or haplotypes in VDR, RXRA, and CYP24A1. We observed no statistically significant associations between polymorphisms or haplotypes in key vitamin D-related genes and risk of breast cancer. These results, combined with the observation in this cohort and most other prospective studies of no association of circulating 25(OHD with breast cancer risk, do not support an association between vitamin D and breast cancer risk.

    Objective: To describe the risk of acute myocardial infarction (AMI) after radiation therapy (RT) for breast cancer (BrCa) in an exposed population. Methods: We identified and validated cases of AMI (vAMI), by electrocardiographic or enzyme criteria, among all 6680 women who received post-operative RT following lumpectomy or mastectomy, within 12 months following diagnosis of BrCa between 1982 and 1988 in Ontario, Canada. We identified women without vAMI whose death certification was ascribed to AMI (dAMI). We abstracted risk factors and treatment exposures for a random sample of women from the 6680, and for all with vAMI or dAMI. The hazards of vAMI and of dAMI were estimated using multivariate Cox proportional hazards models, corrected for study design. Results: We validated 121 cases of vAMI and identified 92 cases of dAMI. The risk of vAMI associated with RT to the left breast HR = 1.96 (1.09, 3.54) among women at age ≥ 60 at time of RT, adjusted for history of smoking and prior MI. The adjusted HR dAMI = 1.90 (1.08, 3.35) for exposure to anterior internal mammary node (IMC) RT. Among women who received anterior left breast boost RT, increasing area of the boost is associated with adjusted HR vAMI = 1.02 (1.00, 1.03)/cm 2 , and adjusted HR dAMI = 1.02 (1.01, 1.03)/cm 2 . Conclusion: The risks of vAMI and dAMI following RT for BrCa are related to anatomic sites of RT (left breast, area of anterior left breast boost field, and anterior IMC field)

    Full Text Available Breast cancer is recognized as a major public health problem in developing countries; however, there is very little evidence of behavioral factors associated with breast cancer risk. This study was conducted to identify lifestyles as risk factors for breast cancer among Central African women. A case-control study was conducted with 174 cases confirmed histologically by the pathology unit of the National Laboratory and 348 age-matched controls. Data collection tools included a questionnaire with interviews and medical records of patients. Data were analyzed using SPSS software version 20. Odd ratio (OR and 95% confidence intervals (95% CI were obtained by unconditional logistic regression. In total, 522 women were studied with a mean age of 45.8 (SD = 13.4 years. By unconditional logistic regression model, women with breast cancer were more likely to have attained illiterate and elementary education level [11.23 (95% CI, 4.65-27.14 and 2.40 (95% CI, 1.15-4.99], married [2.09 (95% CI, 1.18-3.71], positive family history [2.31 (95% CI, 1.36-3.91], radiation exposure [8.21 (95% CI, 5.04-13.38], consumption charcuterie [10.82 (95% CI, 2.39-48.90], fresh fish consumption [4.26 (95% CI, 1.56-11.65], groundnut consumption [6.46 (95% CI, 2.57-16.27], soybean consumption [16.74 (95% CI, 8.03-39.84], alcohol [2.53 (95% CI, 1.39-4.60], habit of keeping money in bras[3.57 (95% CI, 2.24-5.69], overweight [5.36 (95% CI, 4.46-24.57] and obesity [3.11(95% CI, 2.39-20.42]. However, decreased risk of breast cancer was associated with being employed [0.32 (95% CI, 0.19-0.56], urban residence [0.16 (95% CI, 0.07-0.37], groundnut oil consumption [0.05 (95% CI, 0.02-0.14], wine consumption [0.16 (95% CI, 0.09-0.26], non habit of keeping cell phone in bras [0.56 (95% CI, 0.35-0.89] and physical activity [0.71(95% CI, 0.14-0.84].

    Globally, the burden of breast cancer (BC) continues to increase. BC related lymphedema (BCRL) is currently non curable and as a life time risk it affects at least 25% of BC patients. Knowing more about BCRL and appropriate control of its modifiable risk factors can improve quality of life (QOL) of the affected patients. In this case control study to detect factors, 400 women with BCRL (as the case group) and 283 patients with BC without lymphedema (as the control group) that were referred to Shiraz University of Medical Sciences affiliated BC clinic center were assessed. The data were analyzed in SPSS. The mean age of the case group was 52.3±11.0 years and of the control group was 50.1±10.9 years. In patients with BCRL, 203(50.7%) had left (Lt) side BC and in non- lymphedema group 151 (53.3%) had Lt side BC. Out of all BCRL patients, 204 (51%) had lymphedema in all parts of their affected upper extremities, 100 (25%) had swelling in the arm and forearm and 23 (5.7%) had edema in both the upper extremity and trunk. Edema, heaviness, concern about changing body image, pain and paresthesia were the most common signs/symptoms among patients with BCRL. In BCRL patients, the difference of circumference between the affected upper limb and non-affected limb was 4.4±2.5 cm and the difference in volume displacement was 528.7±374.4 milliliters. Multiple variable analysis showed that moderate to severe activity (OR; odds ratio =14, 95% CI: 2.6-73.3 ), invasiveness of BC (OR =13.7, 95% CI: 7.3-25.6), modified radical mastectomy (OR=4.3, 95% CI: 2.3-7.9), BMI =>25 (OR=4.2, 95% CI: 2-8.7), radiotherapy (OR=3.9, 95% CI: 1.8-8.2 ), past history of limb damage (OR=1.7, 95% CI: 0.9-3.1) and the number of excised lymph nodes (OR=1.06, 95% CI: 1.02-1.09) were the significant predictors of lymphedema in women with BC. Modifiable risk factors of BCRL such as non-guided moderate to severe physical activity, high BMI and trauma to the limb should be controlled as early as possible in

    Toll-like receptors (TLRs) and the transcription factor nuclear factor-κB (NFκB) are important in inflammation and cancer. We examined the association between breast cancer risk and 233 tagging single nucleotide polymorphisms within 31 candidate genes involved in TLR or NFκB pathways. This population-based study in the Seattle area included 845 invasive breast cancer cases, diagnosed between 1997 and 1999, and 807 controls aged 65–79. Variant alleles in four genes were associated with breast cancer risk based on gene-level tests: MAP3K1, MMP9, TANK, and TLR9. These results were similar when the risk of breast cancer was examined within ductal and luminal subtypes. Subsequent exploratory pathway analyses using the GRASS algorithm found no associations for genes in TLR or NFκB pathways. Using publicly available CGEMS GWAS data to validate significant findings (N = 1,145 cases, N = 1,142 controls), rs889312 near MAP3K1 was confirmed to be associated with breast cancer risk (P = 0.04, OR 1.15, 95% CI 1.01–1.30). Further, two SNPs in TANK that were significant in our data, rs17705608 (P = 0.05) and rs7309 (P = 0.04), had similar risk estimates in the CGEMS data (rs17705608 OR 0.83, 95% CI 0.72–0.96; CGEMS OR 0.90, 95% CI 0.80–1.01 and rs7309 OR 0.83, 95% CI 0.73–0.95; CGEMS OR 0.91, 95% CI 0.81–1.02). Our findings suggest plausible associations between breast cancer risk and genes in TLR or NFκB pathways. Given the few suggestive associations in our data and the compelling biologic rationale for an association between genetic variation in these pathways and breast cancer risk, further studies are warranted that examine these effects

    Endocrine disrupting chemicals and carcinogens, some of which may not yet have been classified as such, are present in many occupational environments and could increase breast cancer risk. Prior research has identified associations with breast cancer and work in agricultural and industrial settings. The purpose of this study was to further characterize possible links between breast cancer risk and occupation, particularly in farming and manufacturing, as well as to examine the impacts of early agricultural exposures, and exposure effects that are specific to the endocrine receptor status of tumours. 1005 breast cancer cases referred by a regional cancer center and 1146 randomly-selected community controls provided detailed data including occupational and reproductive histories. All reported jobs were industry- and occupation-coded for the construction of cumulative exposure metrics representing likely exposure to carcinogens and endocrine disruptors. In a frequency-matched case-control design, exposure effects were estimated using conditional logistic regression. Across all sectors, women in jobs with potentially high exposures to carcinogens and endocrine disruptors had elevated breast cancer risk (OR = 1.42; 95% CI, 1.18-1.73, for 10 years exposure duration). Specific sectors with elevated risk included: agriculture (OR = 1.36; 95% CI, 1.01-1.82); bars-gambling (OR = 2.28; 95% CI, 0.94-5.53); automotive plastics manufacturing (OR = 2.68; 95% CI, 1.47-4.88), food canning (OR = 2.35; 95% CI, 1.00-5.53), and metalworking (OR = 1.73; 95% CI, 1.02-2.92). Estrogen receptor status of tumors with elevated risk differed by occupational grouping. Premenopausal breast cancer risk was highest for automotive plastics (OR = 4.76; 95% CI, 1.58-14.4) and food canning (OR = 5.70; 95% CI, 1.03-31.5). These observations support hypotheses linking breast cancer risk and exposures likely to include carcinogens and endocrine disruptors, and demonstrate the value of detailed work

    To understand decision making concerning adoption and nonadoption of accelerated partial breast radiotherapy (RT) prior to long-term randomized trial evidence. A total of 36 radiation oncologists and surgeons were recruited through purposive and snowball sampling strategies from September 2010 through January 2013. Semistructured phone interviews were conducted and audio-recorded and lasted 20-45 minutes. Qualitative analysis was conducted using a framework approach, iteratively exploring key concepts and emerging issues raised by subjects. Interviews were transcribed and imported into Atlas.ti v6. Transcripts were independently coded by 3 researchers shortly after each interview, followed by consensus development on each coded transcript. Barriers and facilitators of adoption, practice patterns, and informational/educational sources concerning accelerated partial breast RT were all assessed to determine major themes. Nearly half of physicians were surgeons (47%), and half were radiation oncologists (53%), with 61% overall in urban settings. Twenty-nine of the 36 physicians interviewed used brachytherapy-based partial breast RT. Five major factors were involved in physicians' decisions to adopt accelerated partial breast RT: facilitators encouraging adoption (e.g., enthusiastic colleagues and patient convenience), financial and prestige incentives, pressures to adopt (e.g., potential declines in referrals), judgment concerning acceptable level of scientific evidence, and barriers (e.g., not having appropriate machinery or referral mechanism in place). If technology was adopted, clinical guideline adherence varied. Technology adoption is based on financial and social pressures, along with often-limited scientific evidence and what seems "best" for patients. For technology adoption and diffusion to be rational and evidence-based, we must encourage appropriate financial payment models to curb use outside of research studies and promote development of additional

    In order to reduce the risk of recurrence, adjuvant treatment with an aromatase inhibitor (AI) is recommended for postmenopausal women following surgery for hormone receptor-positive breast cancer. AIs are associated with improved disease-free survival compared with tamoxifen. The adverse events associated with AIs resemble those of menopause, such as bone density loss and musculoskeletal symptoms. We examine the case of a postmenopausal woman who was prescribed anastrozole, a nonsteroidal AI, as adjuvant therapy following surgery for estrogen and progesterone receptor-positive (ER and PgR+) breast cancer. A 58-year-old postmenopausal woman diagnosed with ER and PgR+ breast cancer was prescribed anastrozole as adjuvant therapy following a right-inferior quadrantectomy. After experiencing joint pain and stiffness, she was prescribed paracetamol and a topical nonsteroidal anti-inflammatory drug. She was also counseled on nonpharmacological interventions. However, she continued to experience symptoms, and reported that she was not taking anastrozole regularly. The case study patient ultimately found relief by switching to letrozole, another aromatase inhibitor. This approach is supported by recent studies examining the benefits of switching strategies between aromatase inhibitors in order to relieve symptoms of arthralgia/myalgia. Both adherence and strategies for managing aromatase inhibitor-associated arthralgia are key to deriving maximal clinical benefit from AI therapy. Switching from one aromatase inhibitor to another may provide a viable option in managing adverse events and enhancing adherence to medication

    The X-ray repair cross-complementation group 1 (XRCC1) protein plays an important role in base excision repair. In the present study, we specifically investigated whether common genetic variant in XRCC1 (exon 10, codon Arg399Gln) was associated with an altered risk of breast cancer. The eligible cases were patients at chemotherapy unit of Nemazi hospital, Shiraz Iran, from October 1999 to August 2000 and from July 2004 to July 2005. The present study included 186 females with breast cancer. Age frequency-matched controls were randomly selected from the healthy females blood donor, according to the age distribution of the cases. A total of 187 healthy females included in the study. Using PCR-based method, the XRCC1 Arg399Gln polymorphism was determined. In control group the 399Gln allele frequency was 32.6%. The genotypic frequencies of the control subjects did not show significant deviation from Hardy-Weinberg equilibrium (chi(2) = 1.683, df = 1, P > 0.05). A statistically significant association was observed in comparison between Gln/Gln and Arg/Arg genotype (OR = 2.01, 95% CI:1.02-3.94, P = 0.041). There was no linear trend for presence of 0, 1, and 2 of the 399Gln allele and risk of breast cancer (chi(2) = 1.212, P = 0.271). In the recessive effect of the Gln allele (comparison between Gln/Gln vs. Arg/Arg+Arg/Gln), Gln/Gln genotype significantly increased the risk of breast cancer (OR = 2.31, 95% CI:1.21-4.35, P = 0.010). In the dominant effect of the Gln allele (comparison between Gln/Gln+Arg/Gln vs. Arg/Arg), Gln/Gln+Arg/Gln genotypes was not associated with the risk of breast cancer (OR = 0.95, 95% CI:0.63-1.42, P = 0.799). It is concluded that 399Gln allele may act as a recessive allele and increase the breast cancer risk.

    Mammographic density is a strong risk factor for breast cancer, but its potential application in risk management is not clear, partly due to uncertainties about its interaction with other breast cancer risk factors. We aimed to quantify the impact of mammographic density on breast cancer risk in women aged 40-49 at intermediate familial risk of breast cancer (average lifetime risk of 23%), in particular in premenopausal women, and to investigate its relationship with other breast cancer risk factors in this population. We present the results from a case-control study nested with the FH01 cohort study of 6,710 women mostly aged 40-49 at intermediate familial risk of breast cancer. One hundred and three cases of breast cancer were age-matched to one or two controls. Density was measured by semiautomated interactive thresholding. Absolute density, but not percent density, was a significant risk factor for breast cancer in this population after adjusting for area of nondense tissue (OR per 10 cm(2) = 1.07, 95% CI 1.00-1.15, p = 0.04). The effect was stronger in premenopausal women, who made up the majority of the study population. Absolute density remained a significant predictor of breast cancer risk after adjusting for age at menarche, age at first live birth, parity, past or present hormone replacement therapy, and the Tyrer-Cuzick 10-year relative risk estimate of breast cancer. Absolute density can improve breast cancer risk stratification and delineation of high-risk groups alongside the Tyrer-Cuzick 10-year relative risk estimate. © 2014 UICC.

    Eleven patients with T1 and small T2 breast cancer were treated by a combination of quadrantectomy, axillary dissection and radiotherapy. The mean age of the patients was 44.6 years. Mean follow-up period was 7.1 months. Six patients had clinical stage I, and five patients had clinical stage II. Four patients had involvement of axillary content (36.3%) on histological examination. There were eight scirrhous carcinomas and three papillotubular carcinomas. The incidence of local and distant recurrence was none in our group. The multifocality of breast cancer based on pathologic studies had been shown. On the basis of these findings we concluded that the patients undergoing breast conservation should be subjected to postoperative radiotherapy. Psychological morbidity was compared in 10 patients treated by breast conservation and 23 patients treated by mastectomy. There were no statistically significant differences between two groups in the estimation of adjustment disorder, depression, anxiety and stress. The patients in breast conservation group had a significant excess or nervousness and the patients of the mastectomy group had an anger. (author)

    Full Text Available CONTEXT: Supernumerary breast tissue may be affected by the same diseases and alterations that compromise topical breast tissue. Nevertheless, reports of fibroadenoma in supernumerary breast tissue in the axillae are rare. OBJECTIVE: To describe a case of fibroadenoma in an axillary supernumerary breast. DESIGN: Case report. CASE REPORT: A 39-year-old woman was referred to the gynecology and obstetrics outpatient clinic at Hospital Estadual Sumaré, complaining of bilateral axillary masses. The patient reported cosmetic problems and local pain and discomfort. On physical examination, alterations compatible with bilateral axillary accessory breasts, without palpable nodules, were observed. Supplementary examinations (mammography and ultrasonography revealed a 1.1 cm mass in the right axillary breast. The patient underwent resection of the supernumerary breasts and histopathological examination revealed fibroadenoma of the right axillary breast tissue.

    Full Text Available Abstract Background The identification of the organisation and dynamics of molecular pathways is crucial for the understanding of cell function. In order to reconstruct the molecular pathways in which a gene of interest is involved in regulating a cell, it is important to identify the set of genes to which it interacts with to determine cell function. In this context, the mining and the integration of a large amount of publicly available data, regarding the transcriptome and the proteome states of a cell, are a useful resource to complement biological research. Results We describe an approach for the identification of genes that interact with each other to regulate cell function. The strategy relies on the analysis of gene expression profile similarity, considering large datasets of expression data. During the similarity evaluation, the methodology determines the most significant subset of samples in which the evaluated genes are highly correlated. Hence, the strategy enables the exclusion of samples that are not relevant for each gene pair analysed. This feature is important when considering a large set of samples characterised by heterogeneous experimental conditions where different pools of biological processes can be active across the samples. The putative partners of the studied gene are then further characterised, analysing the distribution of the Gene Ontology terms and integrating the protein-protein interaction (PPI data. The strategy was applied for the analysis of the functional relationships of a gene of known function, Pyruvate Kinase, and for the prediction of functional partners of the human transcription factor TBX3. In both cases the analysis was done on a dataset composed by breast primary tumour expression data derived from the literature. Integration and analysis of PPI data confirmed the prediction of the methodology, since the genes identified to be functionally related were associated to proteins close in the PPI network

    In a consortium including 23 637 breast cancer patients and 25 579 controls of East Asian ancestry, we investigated 70 single-nucleotide polymorphisms (SNPs) in 67 independent breast cancer susceptibility loci recently identified by genome-wide association studies (GWASs) conducted primarily in European-ancestry populations. SNPs in 31 loci showed an association with breast cancer risk at P Asians and provided evidence for associations of breast cancer risk in the East Asian population with nearly half of the genetic risk variants initially reported in GWASs conducted in European descendants. Taken together, these common genetic risk variants explain ∼10% of excess familial risk of breast cancer in Asian populations. PMID:23535825

    Ductal carcinoma in situ (DCIS) is treated to prevent progression to invasive breast cancer. Yet, most lesions will never progress, implying that overtreatment exists. Therefore, we aimed to identify factors distinguishing harmless from potentially hazardous DCIS using a nested case-control study. We conducted a case-control study nested in a population-based cohort of DCIS patients treated with breast conserving surgery (BCS) alone (n=2,658) between 1989-2005. We compared clinical, pathological, and immunohistochemical DCIS characteristics of 200 women who subsequently developed ipsilateral invasive breast cancer (iIBC; cases) and 474 women who did not (controls), in a matched setting. Median follow-up time was 12.0 years (interquartile range 9.0-15.3). Conditional logistic regression models, were used to assess associations of various factors with subsequent iIBC risk after primary DCIS. High COX-2 protein expression showed the strongest association with subsequent iIBC (odds ratio [OR]=2.97, 95% confidence interval [95%CI] 1.72-5.10). In addition, HER2 overexpression (OR=1.56, 95%CI 1.05-2.31) and presence of periductal fibrosis (OR=1.44, 95%CI 1.01-2.06) were associated with subsequent iIBC risk. Patients with HER2+/COX-2high DCIS had a 4-fold higher risk of subsequent iIBC (vs. HER2-/COX-2low DCIS), and an estimated 22.8% cumulative risk of developing subsequent iIBC at 15 years. With this unbiased study design and representative group of DCIS patients treated by BCS alone, COX-2, HER2, and periductal fibrosis were revealed as promising markers predicting progression of DCIS into iIBC. Validation will be done in independent data sets. Ultimately, this will aid individual risk stratification of women with primary DCIS. Copyright ©2018, American Association for Cancer Research.

    Breast implants used for augmentation mammoplasty or breast reconstruction could rupture from various causes such as trauma or spontaneous failure. The objectives of this study were to investigate the relationships between the causes of implant rupture and the degree of capsular contracture, and then to evaluate the relative efficacies of specific signs on magnetic resonance imaging (MRI) known to be beneficial for diagnosing the rupture. A retrospective review identified patients with prosthetic implant rupture or impending rupture treated by the senior author. The 30 cases of implant rupture available for review were classified into two groups: intracapsular and extracapsular ruptures. The 30 cases of breast implant ruptures were analyzed with respect to the clinical symptoms and signs, the causes of rupture, the degree of capsular contracture, and therapeutic plans. Among the 30 cases, 14 patients who had undergone MRI during the diagnostic period were analyzed with respect to the relationships between MRI readings and operative findings. Spontaneous rupture of membranes was most common (80%), followed by failure because of trauma (7%) and valve or implant base (4%). The symptoms during implant rupture were contour deformity, palpated mass-like lesions, pain, and focal inflammation. According to the analysis of specific MRI signs, the sensitivity and specificity of the linguine sign were 87% and 100%, respectively, for intracapsular rupture. For extracapsular rupture, the sensitivity and specificity of the linguine sign were, respectively, 67% and 75%. The sensitivity and specificity of the rat-tail sign and tear drop sign were 14% and 50%, respectively. Breast implant rupture was correlated with the degree of capsular contracture in our study. Among the various specific MRI signs used in diagnosing the rupture, the linguine sign was reliable and had a high sensitivity and specificity, especially in cases of intracapsular rupture. On the other hand, the rat

    Full Text Available Today, tamoxifen is one of the world's best-selling hormonal breast cancer drugs. However, it was not always so. Compound ICI 46,474 (as it was first known was synthesized in 1962 within a project to develop a contraceptive pill in the pharmaceutical laboratories of ICI (now part of AstraZeneca. Although designed to act as an anti-estrogen, the compound stimulated, rather than suppressed ovulation in women. This, and the fact that it could not be patented in the USA, its largest potential market, meant that ICI nearly stopped the project. It was saved partly because the team's leader, Arthur Walpole, threatened to resign, and pressed on with another project: to develop tamoxifen as a treatment for breast cancer. Even then, its market appeared small, because at first it was mainly used as a palliative treatment for advanced breast cancer. An important turning point in tamoxifen's journey from orphan drug to best-selling medicine occurred in the 1980s, when clinical trials showed that it was also useful as an adjuvant to surgery and chemotherapy in the early stages of the disease. Later, trials demonstrated that it could prevent its occurrence or re-occurrence in women at high risk of breast cancer. Thus, it became the first preventive for any cancer, helping to establish the broader principles of chemoprevention, and extending the market for tamoxifen and similar drugs further still. Using tamoxifen as a case study, this paper discusses the limits of the rational approach to drug design, the role of human actors, and the series of feedback loops between bench and bedside that underpins pharmaceutical innovation. The paper also highlights the complex evaluation and management of risk that are involved in all therapies, but more especially perhaps in life-threatening and emotion-laden diseases like cancer.

    Previous studies and biological mechanisms of carcinogenesis suggest that the steroid receptor content of benign breast epithelium may be related to breast cancer risk. The objective in this study was to compare the levels of estrogen receptor-α (ER) and progesterone receptor (PR) in nonneoplastic breast epithelium between breast cancer cases and biopsy controls. Between 1995 and 1997 at two sites (Women's College Hospital in Toronto and Kingston General Hospital), 667 women who were scheduled for diagnostic excisional breast biopsies completed a questionnaire providing personal information and agreed to allow analysis of routinely resected tissue. Histological slides with nonneoplastic epithelium were available for 101 cancer cases and 200 biopsy controls in Toronto and for 105 cancer cases and 119 controls in Kingston. Nonneoplastic epithelium was examined with immunohistochemical assays to determine the percent of epithelial cells staining for ER and PR. Unconditional logistic regression was used to calculate odds ratios (OR) stratified by study site. The ER content of nonneoplastic tissue was higher in cases than biopsy controls in unadjusted analyses; after adjustment for age, however, a weak association remained in only one of the study sites. After adjustment for age, the PR content of nonneoplastic tissue was slightly lower in breast cancer cases than controls in one study site. Furthermore, this inverse association was confined to women with PR negative breast cancer in comparison to the controls. No interaction between ER and PR content of nonneoplastic tissue was observed in relation to the odds of having breast cancer. The results of this study are consistent with only a slight indication of increased ER levels in nonneoplastic tissue in breast cancer cases relative to controls. This study contributes to the understanding of breast cancer by examining both ER and PR in nonneoplastic tissue. Limitations remain, however, such as the necessity of

    There has been an increase in the incidence of breast cancer in China, but no definite risk and protective factors for breast cancer have been identified in Chinese females. This study was designed to identify the risk factors for female breast cancer in North and East China. A 1:3 matched, case-control study was conducted. All of the subjects in the case and control groups were selected from a previous epidemiological survey of 122 058 females aged 25 to 70 years. Single and multiple Logistic regression analyses were used to study potential factors in the development of breast cancer. Significant differences at the level of α=0.20 between case and control groups were observed for the following factors: economic status, social status, family annual income, bean product consumption, body mass index (BMI), family history of breast cancer in the first or second degree, number of miscarriages, menstrual pattern, benign breast disease history, nipple leakage, inverted nipple, history of diabetes mellitus, history of hypertension, history of ovarian cyst, physical exercise, current and global quality of life satisfaction, healthy behavior and prevention, and scores of breast cancer-related knowledge. After Cox-regression model analysis (α=0.10), six factors were found to be significantly related to breast cancer, of which the ORs and 95%CIs were: BMI, 1.696 (1.169-2.460, P=0.005); benign breast disease history, 2.672 (0.848-8.416, P=0.093); family history of breast cancer, 7.080 (1.758-28.551, P=0.006); number of miscarriages, 1.738 (1.014-2.978, P=0.044); global quality of life satisfaction, 3.044 (1.804-5.136, P=0.000); healthy behavior and prevention, 3.294 (1.692-6.412, P=0.000). A comprehensive range of factors related to breast cancer was identified. Women should be educated about a healthy lifestyle, especially those with a family history of breast cancer or a personal history of benign breast disease.

    The relationship between breast cancer and organochlorine exposure is controversial and complex. As estrogen receptor positive and negative breast cancer may represent different entities of the disease, this study was undertaken to evaluate organochlorines influence on breast cancer risk and survival according to receptor status. The background material stems from the Copenhagen City Heart Study (Denmark 1976-78). The breast cancer risk was investigated in a cohort nested case-control design including 161 cases and twice as many breast cancer free controls. The cases served as a cohort in the survival analysis. Serum organochlorine concentrations were determined by gaschromotography. The observed increased breast cancer risk associated with exposure to dieldrin derived from women who developed an estrogen receptor negative (ERN) tumor (Odds ratio [OR] I vs. IV quartile, 7.6, 95% confidence interval [95% CI] 1.4-46.1, p-value for linear trend 0.01). Tumors in women with the highest dieldrin serum level were larger and more often spread at the time of diagnosis than ERP tumors. The risk of dying was for the remaining evaluated compounds higher among patients with ERP breast cancer when compared to those with ERN. In the highest quartile of polychlorinated biphenyls (ΣPCB) it was more than 2-fold increased (Relative risk [RR] I vs. IV quartile, 2.5, 95% CI 1.1-5.7), but no dose-response relation was apparent. The results do not suggest that exposure to potential estrogenic organochlorines leads to development of an ERP breast cancer. A possible adverse effect on prognosis of hormone-responsive breast cancers needs to be clarified

    Background. The differential diagnosis of primary breast tuberculosis with other benign or malignant conditions can be difficult with the current imaging techniques that used to recognize breast pathologies. In many cases mammographic and ultrasound characteristics of breast tuberculosis are similar to those of breast cancer. Case report. We present a case of primary breast tuberculosis, with no previous history of the disease, which was diagnosed during the operation. Conclusions. Primary breast tuberculosis can be misdiagnosed. In these cases a tuberculosis infection history is negative, the mammographic and radiological findings obscure and the mass can be misdiagnosed as carcinoma. The diagnosis is achieved after the surgical removal of the mass and histological examination of the specimen. (author)

    Estimating a woman's risk of breast cancer is becoming increasingly important in clinical practice. Mammographic density, estimated as the percent of dense (PD) tissue area within the breast, has been shown to be a strong risk factor. Studies also support a relationship between mammographic texture and breast cancer risk. We have developed a fullyautomated software pipeline for computerized analysis of digital mammography parenchymal patterns by quantitatively measuring both breast density and texture properties. Our pipeline combines advanced computer algorithms of pattern recognition, computer vision, and machine learning and offers a standardized tool for breast cancer risk assessment studies. Different from many existing methods performing parenchymal texture analysis within specific breast subregions, our pipeline extracts texture descriptors for points on a spatial regular lattice and from a surrounding window of each lattice point, to characterize the local mammographic appearance throughout the whole breast. To demonstrate the utility of our pipeline, and optimize its parameters, we perform a case-control study by retrospectively analyzing a total of 472 digital mammography studies. Specifically, we investigate the window size, which is a lattice related parameter, and compare the performance of texture features to that of breast PD in classifying case-control status. Our results suggest that different window sizes may be optimal for raw (12.7mm2) versus vendor post-processed images (6.3mm2). We also show that the combination of PD and texture features outperforms PD alone. The improvement is significant (p=0.03) when raw images and window size of 12.7mm2 are used, having an ROC AUC of 0.66. The combination of PD and our texture features computed from post-processed images with a window size of 6.3 mm2 achieves an ROC AUC of 0.75.

    Early breast cancer follow-up guidelines for patients who underwent surgery suggest a regular and accurate clinical examination of the breast area, for an early identification of cutaneous or subcutaneous breast cancer relapse. Nonetheless, breast skin lesions arising in patients treated with mastectomy for breast cancer can be caused by several diseases. A series of diagnostic hypotheses should be considered, not only focusing on cutaneous metastasis, but also on dermatologic and systemic diseases. In February 2015, a 37-year-old patient underwent a right subcutaneous mastectomy for stage IIA breast cancer. Five months after beginning adjuvant chemotherapy, she noted hyperpigmentation and thickening of the skin on the right breast. Differential diagnosis included local relapse, skin infection, lymphoma, or primary cutaneous disease, and a skin biopsy was performed. The histopathologic specimen showed full-thickness sclerosis, with features of localized morphea. Therapy with clobetasol was prescribed, with progressive resolution of the thickness. The collaboration between many professionals in a multidisciplinary team (oncologist, dermatologist, plastic surgeon, and pathologist) was crucial to achieving the diagnosis. In the literature, some articles describe correlation between connective tissue diseases and silicone breast implants, but the pathogenetic mechanisms are unknown. We report a rare case of breast morphea after positioning a silicone implant in a patient who had undergone mastectomy. This clinical report represents an interesting model of multidisciplinary management of a patient with breast cancer who developed an uncommon dermatologic disease. Further studies are needed to clarify the association between silicone implants and breast morphea.

    This study was conducted to identify reproductive and dietary factors associated with benign proliferative mammary epithelial cell changes. Subjects were women enrolled in a randomized trial of breast self-examination in Shanghai, China. Women who developed fibrocystic breast conditions classified as nonproliferative (175 women), proliferative (181 women), or proliferative with atypia (33 women) between 1995 and 2000 and 1,070 unaffected trial participants were administered general risk factor and food frequency questionnaires. Conditional logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. High parity and consumption of fresh fruits and vegetables were more strongly associated with a reduced risk of proliferative and atypical lesions than with nonproliferative conditions. For the fourth quartile of consumption versus the first, odds ratios for lesions diagnosed as nonproliferative, proliferative, and proliferative with atypia were 0.4 (95% confidence interval (CI): 0.2, 0.7), 0.2 (95% CI: 0.1, 0.4), and 0.1 (95% CI: 0.03, 0.5), respectively, for fruit intake and 0.6 (95% CI: 0.3, 1.1), 0.4 (95% CI: 0.2, 0.7), and 0.1 (95% CI: 0.1, 0.9), respectively, for vegetable intake. Reduced but nonsignificant risks in relation to soy products were observed for proliferative and atypical lesions. No single nutrient or botanical family was appreciably more strongly associated with proliferative conditions than with nonproliferative conditions, after results were controlled for total fruit and vegetable consumption. A diet rich in fruits and vegetables may reduce cellular proliferation in the mammary epithelium; this is one mechanism by which such a diet could reduce risk of breast cancer.

    Schwannoma (neurilemoma) is a benign nerve tumor derived from the nerve sheath. The most common locations are the flexor surfaces of the extremities, and the head and the neck. Schwannoma of the breast is unusual. To our knowledge, few studies have reported the radiologic appearance of Schwannoma in the breast and there has been only one report from Korea (1-3). This tumor can be clinically and radiologically considered to be fibroadenoma, which is a common benign tumor of the breast. We describe the mammographic and sonographic findings of a case of Schwannoma in the breast.

    Nitrate is a precursor in the endogenous formation of N-nitroso compounds, which are potent animal carcinogens, whereas antioxidant vitamins have been suggested to protect against carcinogenesis. Interestingly, nitrate and antioxidant vitamins stem from the same dietary sources. We investigated whether the intake of nitrate relative to antioxidant vitamins is associated with the risk of breast cancer. A total of 362 breast cancer cases were matched to the 362 controls by age and menopausal status. Dietary intake was assessed using a quantitative food frequency questionnaire with 121 food items by trained interviewers. The nitrate to antioxidant vitamin consumption ratio was then calculated. Conditional logistic regression analysis was used to obtain odds ratios (ORs) and corresponding 95% confidence intervals (CI). Mean intakes of nitrate for cases and controls were 421 mg/day and 424 mg/day, respectively. Intakes of nitrate, nitrate/beta-carotene, nitrate/vitamin C, and nitrate/vitamin E were not associated with breast cancer risk. However, higher breast cancer risk was observed with higher intake of nitrate/folate (OR = 2.03, 95% CI = 1.16-3.54, P for trend = 0.052). Our results suggest that lowering the ratio of nitrate to folate intake may be effective in reducing breast cancer risk.

    Mammographic density has been shown to be a strong independent predictor of breast cancer and a causative factor in reducing the sensitivity of mammography. There remain questions as to the use of mammographic density information in the context of screening and risk management, and of the association with cancer in populations known to be at increased risk of breast cancer. To assess the association of breast density with presence of cancer by measuring mammographic density visually as a percentage, and with two automated volumetric methods, Quantra™ and VolparaDensity™. The TOMosynthesis with digital MammographY (TOMMY) study of digital breast tomosynthesis in the Breast Screening Programme of the National Health Service (NHS) of the United Kingdom (UK) included 6020 breast screening assessment cases (of whom 1158 had breast cancer) and 1040 screened women with a family history of breast cancer (of whom two had breast cancer). We assessed the association of each measure with breast cancer risk in these populations at enhanced risk, using logistic regression adjusted for age and total breast volume as a surrogate for body mass index (BMI). All density measures showed a positive association with presence of cancer and all declined with age. The strongest effect was seen with Volpara absolute density, with a significant 3% (95% CI 1-5%) increase in risk per 10 cm 3 of dense tissue. The effect of Volpara volumetric density on risk was stronger for large and grade 3 tumours. Automated absolute breast density is a predictor of breast cancer risk in populations at enhanced risk due to either positive mammographic findings or family history. In the screening context, density could be a trigger for more intensive imaging. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Overexpression of the HER2 proto-oncogene in human cancer cells has been associated with a poor prognosis, and survival improves with therapy targeting the HER2 gene. Animal studies and protein modeling suggest that the Ile655Val polymorphism located in the transmembrane domain of the HER2 protein might influence breast cancer development by altering the efficiency of homodimerization. To investigate this genetic polymorphism, incident cases of invasive breast cancer (N = 1,094) and population controls of a similar age (N = 976) were interviewed during 2001 to 2003 regarding their risk factors for breast cancer. By using DNA collected from buccal samples mailed by the participants, the HER2 Ile655Val polymorphism was evaluated with the Applied Biosystems allelic discrimination assay. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated by logistic regression adjusted for numerous breast cancer risk factors. Analysis was restricted to women with self-reported European descent. Prevalence of the Val/Val genotype was 5.6% in cases and 7.1% in controls. In comparison with the Ile/Ile genotype, the Ile/Val genotype was not significantly associated with breast cancer risk (OR 0.97, 95% CI 0.79 to 1.18), whereas the Val/Val genotype was associated with a reduced risk (OR 0.63, 95% CI 0.42 to 0.92). This inverse association seemed strongest in older women (OR 0.51, 95% CI 0.29 to 0.89 for women aged more than 55 years), women without a family history of breast cancer (OR 0.54, 95% CI 0.35 to 0.84), postmenopausal women with greater body mass index (OR 0.43, 95% CI 0.20 to 0.91 for a body mass index of 25.3 kg/m 2 or more), and cases diagnosed with non-localized breast cancer (OR 0.49, 95% CI 0.26 to 0.90). Although results from our population-based case-control study show an inverse association between the HER2 Ile655Val polymorphism and risk of invasive breast cancer, most other studies of this single-nucleotide polymorphism suggest an overall null

    Full Text Available Breast cancer in young women is quite uncommon and shows more aggressive characteristics with major disparities between worldwide populations. Prognosis and outcome of breast cancer in young patients are widely studied, but still no consensus is available.We retrospectively included 716 cases of breast cancer women diagnosed in 2009 at the National Institute of Oncology of Rabat. Patients were divided into two groups according to their age: women aged ≤40 years (Group 1 and women aged >40 years (Group 2. Data were recorded from patients' medical files and analyzed using SPSS 13.0 software (IBM.Young patients represent 24.9% of all patients with breast cancer. The comparison between the two groups displayed significant differences regarding nulliparity (p = 0.001 and progesterone receptor negativity (p = 0.01. Moreover, more progression (Metastases/Relapse was registered in young women as compared to older women with breast cancer (p = 0.03. The estimated median follow-up period was 31 months. The 5-years Event-Free Survival (EFS of patients with local disease was 64.6% in young women and 71.5% in older women with breast cancer (p = 0.04. Multivariate analysis in young women showed that nulliparity (HR: 7.2; 95%CI: 1.16-44.54; p = 0.03, T3 tumors (HR: 17.39; 95%CI: 1.74-173.34; p = 0.01 and negative PgR status (HR: 19.85; 95%CI: 1.07-366.54; p = 0.04 can be considered as risk factors for poorer event free survival while hormone therapy was associated with better EFS (HR: 0.11; 95%CI: 0.00-0.75; p = 0.03. In Group 2, multivariate analysis showed that patients with inflammatory breast cancer, N+ status, absence of radiotherapy, absence of chemotherapy, and absence of hormone therapy are at increased risk of recurrence.In Morocco, breast cancer is more frequent in young women as compared to western countries. Breast cancer in young women is more aggressive and is diagnosed late, leading to an intensive treatment. Moreover, the main factors

    Full Text Available Background: Primary leiomyosarcoma (LMS of the breast is a very rare neoplasm of the breast arising from the mesenchymal tissue. The clinical presentation of this entity simulates other benign and malignant lesions of mesenchymal tissue of the breast.Case presentation: Case 1: A 40-year-old female presented with a right-sided breast lump, which was suspected to be a malignant spindle cell tumor on needle core biopsy (NCB. A multi-disciplinary team performed modified radical mastectomy (MRM with axillary node dissection on the patient with no post-operative chemo-radiation. Case 2: A 70-year-old female presented with a left sided breast lump and a palpable axillary node. Needle core biopsy diagnosed it as malignant spindle cell tumor. The patient underwent MRM with axillary node dissection. It was confirmed to be a case of breast LMS with axillary nodal metastasis. Both patients were followed up for one year with no evidence of recurrence.Conclusion: Both cases underwent MRM with axillary node dissection in our study. However, the role of axillary dissection in the prognosis and disease-free survival of the patients with primary LMS of the breast with axillary metastasis has not been studied yet. The optimal management of this entity remains to be tumor excision with clear margins.

    Full Text Available Background: Breast lump is a very common clinical presentation for which fine needle aspiration cytology is often sought for. Because of it’s significant diagnositic value, FNAC has become a routine tool in the evaluation of the nature of the lesion. The objective of this study was to determine the cytomorphological patterns of breast lump in eastern part of Nepal among individuals attending Nobel Medical College. Materials and Methods: This was a retrospective descriptive study done in department of pathology from December 2012 to June 2015. All individuals presenting with breast lumps was included in this study. FNAC was done as per standard procedure and categorized as per United Kingdom National Health Survey Breast Screening Programme (UK-NHS-BSP categories and further also categorized in to neoplastic and non-neolastic categories. Results: We studied 771 cases of breast lumps. Occurrence of breast lump was more common in female (97.4%. Neoplastic lesions accounted for 84.1% of cases out of which benign comprised of 94.6% and malignant comprised of 5.6%. Common benign lesions observed were that of fibroadenona (264 and fibrocystic changes (204. Ductal carcinoma was the most common malignant lesions. All malignant lesions were observed in older age and female sex population.Conclusion: Most of the cases of breast lumps are benign in nature and very few accounted for malignant cases. There is predominance of benign lesions in young age and increased malignancy in older age and female population.

    Prostate, breast and colorectal cancer are the most common tumours in Spain. The aim of the present study was to evaluate the association between adherence to nutrition-based guidelines for cancer prevention and prostate, breast and colorectal cancer, in the MCC-Spain case-control study. A total of 1,718 colorectal, 1,343 breast and 864 prostate cancer cases and 3,431 population-based controls recruited between 2007 and 2012, were included in the present study. The World Cancer Research Fund/American Institute for Cancer Research (WCRC/AICR) score based on six recommendations for cancer prevention (on body fatness, physical activity, foods and drinks that promote weight gain, plant foods, animal foods and alcoholic drinks; score range 0-6) was constructed. We used unconditional logistic regression analysis adjusting for potential confounders. One-point increment in the WCRF/AICR score was associated with 25% (95% CI 19-30%) lower risk of colorectal, and 15% (95% CI 7-22%) lower risk of breast cancer; no association with prostate cancer was detected, except for cases with a Gleason score ≥7 (poorly differentiated/undifferentiated tumours) (OR 0.87, 95% CI 0.76-0.99). These results add to the wealth of evidence indicating that a great proportion of common cancer cases could be avoided by adopting healthy lifestyle habits. © 2017 UICC.

    The relation between suicidal ideation versus hopelessness/helplessness in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared to date in a prospective study. We, therefore, investigated suicidal ideation versus hopelessness/helplessness in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus suicidal/pessimistic thoughts before any diagnostic procedures were carried-out. In the self-rating score (SRS), hopelessness and the helplessness versus pessimistic thoughts were significantly correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa-values for hopelessness versus pessimistic thoughts in the BBD group were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus pessimistic thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus pessimistic thoughts in the HSS and BBD groups. In SRS, the hopelessness and the helplessness versus suicidal thoughts were significantly correlated in the HSS, BBD and BC groups. There was also a significant positive correlation in the ERS in the hopelessness versus suicidal thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus suicidal thoughts in the BBD group. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness versus suicidal/pessimistic thoughts in the self-rating and examiner-rating. In the breast cancer diagnostic Unit, the identification of suicidal ideation is essential in suicide prevention and it is important to assess and treat depression even though a subject reports little suicidal ideation.

    Full Text Available Abstract Background Setting priorities for the funding of new anti-cancer agents is becoming increasingly complex. The funding of adjuvant trastuzumab for breast cancer has brought this dilemma to the fore. In this paper we review external factors that may influence decision-making bodies and present a case study of media response in Ontario, Canada to adjuvant trastuzumab for breast cancer. Methods A comprehensive search of the databases of Canadian national and local newspapers and television was performed. Articles pertaining to trastuzumab in adjuvant breast cancer as well as 17 other anti-cancer drugs and indications were retrieved. The search period was from the date when individual trial results were announced to the date funding was made available in Ontario. Results During the 2.6 months between the release of the trastuzumab results to funding approval in Ontario, we identified 51 episodes of media coverage. For the 17 other drugs/indications (7 breast and 10 non-breast, the median time to funding approval was 31 months (range 14–46. Other recent major advances in oncology such as adjuvant vinorelbine/cisplatin for resected NSCLC and docetaxel for advanced prostate cancer received considerably less media attention (17 media reports for each than trastuzumab. The median number of media reports for breast cancer drugs was 4.5 compared to 2.5 for non-breast cancer drugs (p = 0.56. Conclusion Priority-setting for novel anti-cancer agents is a complex process that tries to ensure fair use of constrained resources to fund therapies with the best evidence of clinical benefit. However, this process is subject to external factors including the influence of media, patient advocates, politicians, and industry. The data in this case study serve to illustrate the significant involvement one (or all of these external factors may play in the debate over priority-setting.

    Two main research efforts in early detection of breast cancer include the development of software tools to assist radiologists in identifying abnormalities and the development of training tools to enhance their skills. Medical image analysis systems, widely known as Computer-Aided Diagnosis (CADx) systems, play an important role in this respect. Often it is important to determine whether there is a benefit in including computer-processed images in the development of such software tools. In this paper, we investigate the effects of computer-processed images in improving human performance in ultrasound breast cancer detection (a perceptual task) and classification (a cognitive task). A survey was conducted on a group of expert radiologists and a group of non-radiologists. In our experiments, random test images from a large database of ultrasound images were presented to subjects. In order to gather appropriate formal feedback, questionnaires were prepared to comment on random selections of original images only, and on image pairs consisting of original images displayed alongside computer-processed images. We critically compare and contrast the performance of the two groups according to perceptual and cognitive tasks. From a Receiver Operating Curve (ROC) analysis, we conclude that the provision of computer-processed images alongside the original ultrasound images, significantly improve the perceptual tasks of non-radiologists but only marginal improvements are shown in the perceptual and cognitive tasks of the group of expert radiologists.

    Studies investigating possible associations between cytochrome P4501B1 (CYP1B1) polymorphisms and breast cancer risk have been inconsistent. We set out to ascertain whether there might be an association between polymorphisms in exon 2 (codon 119, G→T) and exon 3 (codon 432, G→C) of CYP1B1 and breast cancer in a Chinese Han population in the rural region of Ningxia. Using an allele-specific polymerase chain reaction method and direct DNA sequencing, the presence or absence of the two CYP1B1 polymorphisms was investigated. Genotype and allele frequencies were analyzed in breast cancer cases (n = 152) and healthy age-matched controls (n = 156). The odds ratio (OR) of 119G→T or 432G→C in breast cancer cases and controls was 3.3 (95% CI: 1.28 to 8.28) and 2.8 (95% CI: 1.04 to 7.51), respectively. In addition, the OR for people with both polymorphisms (119T and 432C) was 4.69 (95% CI: 1.97 to 11.19). Our results suggest that certain polymorphisms in the CYP1B1 gene might increase risk for breast cancer among Han Chinese, perhaps because they influence the efficiency of CYP1B1 bio-transformation of oestrogens or pro-carcinogens into DNA-reactive electrophiles that may act as cancer-initiating agents.

    Breast cancer (BrCa) is the most frequently diagnosed cancer among females and second cancer after lung cancer in many societies. In Iran, the risk for BrCa is 1 in 35 and each year, 8000 new patients have been diagnosed with BrCa. Studies have shown that dietary components are implicated in the etiology of BrCa. The Index of Nutritional Quality (INQ) is a method of quantitative and qualitative analysis of single foods, meals, and diets. The aim of this study was to determine the usefulness of INQs in predicting BrCa risk. Our case-control study was conducted from March 2015 to February 2016. The study included 145 cases and 148 controls who attended the Shahid Beheshti University of Medical Sciences Cancer Research Center. INQ scores were computed based on dietary intake using a validated 168-item food frequency questionnaire. Logistic regression models were used to estimate multivariable odds ratios adjusted body mass index, education, employment, marital status, menarche age, childbirth number, smoking, menopause status, and physical activity. Vitamins A, C, B 1 , B 2 , and B 12 and selenium INQs as a continuous variable in relation to risk for BrCa showed a significant association after multivariate adjustment (odds ratio [OR] vitA , 0.41 [0.27-0.64]; OR vitC , 0.30 [0.20-0.47]; OR vitB1 , 0.08 [0.04-0.17]; OR vitB2 , 0.19 [0.11-0.34]; OR vitB12 , 0.44 [0.31-0.61]; and OR selenium , 0.42 [0.26-0.67]). Women who consumed a healthier diet including vitamin A, β-carotene, vitamin C, and folate and low-fat milk were at decreased risk for developing BrCa compared with those whose diet included more high fat and lamb meat.

    It has been suggested that recall bias may explain the discrepant results between case-control and cohort studies on diet and the risk of breast cancer. Two control groups were used for this case-control study of 25 to 75-year-old breast cancer cases (n = 310). The first group consisted of population controls drawn from the Finnish National Population Register (n = 454). The second group consisted of women who were referred to the same examinations as were the cases because of clinical suspicion of breast disease but who were later diagnosed as healthy (referral controls; n = 506). Because the diagnosis was unknown at the time of interview, it was possible to assess by comparing the two control groups whether the self-reporting of diet changed under the threat of disease. Dietary habits were examined using a validated, self-administered food-frequency questionnaire. Premenopausal women misreported their consumption of liquid milk products, tea, and sugar. Reporting bias was also associated with the intake of fat and vitamins. Postmenopausal women misreported consumption of milk products. When recall bias was taken into consideration, milk was associated with increased risk of premenopausal breast cancer, whereas high consumption of poultry or high intake of monounsaturated fatty acids, n-3 fatty acids, n-6 fatty acids, and vitamin E were related to lower risk. The study suggested that oil, milk, cheese, coffee and beta-carotene may act as protective factors in postmenopausal women, whereas butter and cream may be risk factors for breast cancer. In summary, it is possible that some food items may be overreported or underreported under the threat of disease in health-conscious population. However, most of the results in this study were not modified by recall bias.

    The aim of this study was to investigate the areas of depression, anxiety, and social support using the structural model of the social network. By comparing the networks of two samples of breast cancer sufferers and healthy control participants, it was possible to identify differences in their relationships, in the shape of the networks themselves, and in the levels of depression and anxiety. Women with breast cancer described smaller and denser networks, including mainly kins whereas the healthy women included more friends, coworkers, and leisure companions. The levels of anxiety and depression were higher in women with breast cancer. Social network and social support measure correlated differently with depression and anxiety in the two groups.

    Night shift work has been suspected to increase breast cancer risk but epidemiological studies have been inconsistent due to heterogeneous assessment of exposure to night work. To overcome this limitation, we pooled data of five population-based case-control studies from Australia, Canada, France, Germany, and Spain into a single harmonized dataset using a common definition of night work including 6093 breast cancer cases and 6933 population controls. The odds ratio for breast cancer in women who ever worked at night for at least 3 h between midnight and 5 a.m. as compared to never night workers was 1.12 (95% CI 1.00-1.25). Among pre-menopausal women, this odds ratio was 1.26 [1.06-1.51], increasing to 1.36 [1.07-1.74] for night shifts ≥ 10 h, 1.80 [1.20-2.71] for work ≥ 3 nights/week, and 2.55 [1.03-6.30] for both duration of night work ≥ 10 years and exposure intensity ≥ 3 nights/week. Breast cancer risk in pre-menopausal women was higher in current or recent night workers (OR = 1.41 [1.06-1.88]) than in those who had stopped night work more than 2 years ago. Breast cancer in post-menopausal women was not associated with night work whatever the exposure metric. The increase in risk was restricted to ER+ tumors, particularly those who were both ER+ and HER2+ . These results support the hypothesis that night shift work increases the risk of breast cancer in pre-menopausal women, particularly those with high intensity and long duration of exposure. Risk difference between pre- and post-menopausal women deserves further scrutiny.

  11. Risk of breast cancer by type of menopausal hormone therapy: a case-control study among post-menopausal women in France.

    Emilie Cordina-Duverger

    Full Text Available BACKGROUND: There is extensive epidemiological evidence that menopausal hormone therapy (MHT increases breast cancer risk, particularly combinations of estrogen and progestagen (EP. We investigated the effects of the specific formulations and types of therapies used by French women. Progestagen constituents, regimen (continuous or sequential treatment by the progestagen, and time interval between onset of menopause and start of MHT were examined. METHODS: We conducted a population-based case-control study in France in 1555 menopausal women (739 cases and 816 controls. Detailed information on MHT use was obtained during in-person interviews. Odds ratios and 95% confidence interval adjusted for breast cancer risk factors were calculated. RESULTS: We found that breast cancer risk differed by type of progestagen among current users of EP therapies. No increased risk was apparent among EP therapy users treated with natural micronized progesterone. Among users of EP therapy containing a synthetic progestin, the odds ratio was 1.57 (0.99-2.49 for progesterone-derived and 3.35 (1.07-10.4 for testosterone-derived progestagen. Women with continuous regimen were at greater risk than women treated sequentially, but regimen and type of progestagen could not be investigated independently, as almost all EP combinations containing a testosterone-derivative were administered continuously and vice-versa. Tibolone was also associated with an increased risk of breast cancer. Early users of MHT after onset of menopause were at greater risk than users who delayed treatment. CONCLUSION: This study confirms differential effects on breast cancer risk of progestagens and regimens specifically used in France. Formulation of EP therapies containing natural progesterone, frequently prescribed in France, was not associated with increased risk of breast cancer but may poorly protect against endometrial cancer.

    Full Text Available Abstract Background Preoperative chemotherapy (PCT has become the standard of care in locally advanced breast cancer. The identification of patient-specific tumor characteristics that can improve the ability to predict response to therapy would help optimize treatment, improve treatment outcomes, and avoid unnecessary exposure to potential toxicities. This study is to determine whether selected biomarkers could predict pathologic response (PR of breast tumors to three different PCT regimens, and to identify a subset of patients who would benefit from a given type of treatment. Methods 118 patients with primary breast tumor were identified and three PCT regimens including DEC (docetaxel+epirubicin+cyclophosphamide, VFC (vinorelbine/vincristine+5-fluorouracil+cyclophosphamide and EFC (epirubicin+5-fluorouracil+cyclophosphamide were investigated. Expression of steroid receptors, HER2, P-gp, MRP, GST-pi and Topo-II was evaluated by immunohistochemical scoring on tumor tissues obtained before and after PCT. The PR of breast carcinoma was graded according to Sataloff's classification. Chi square test, logistic regression and Cochran-Mantel-Haenszel assay were performed to determine the association between biomarkers and PR, as well as the effectiveness of each regimen on induction of PR. Results There was a clear-cut correlation between the expression of ER and decreased PR to PCT in all three different regimens (p p Conclusion ER is an independent predictive factor for PR to PCT regimens including DEC, VFC and EFC in primary breast tumors, while HER2 is only predictive for DEC regimen. Expression of PgR, Topo-II, P-gp, MRP and GST-pi are not predictive for PR to any PCT regimens investigated. Results obtained in this clinical study may be helpful for the selection of appropriate treatments for breast cancer patients.

    Full Text Available Lymphedema is defined as a persistent increase of tissue volume caused by the blocked or absent lymphatic drainage. The purpose of this study is to analyse the effectiveness of lymphatic drainage in the treatment of lymphedema after a mastectomy, with the aim of reducing the volume of the lymphedema and improving overall symptomatology, as well as providing information regarding the impact of this treatment on quality-of-life and the physical limitations of these patients. With these objectives in mind, a series of articles evaluating the effectiveness of manual lymphatic drainage in the case of patients with breast cancer and lymphedema have been studied. The parameters under observation were: duration of lymphedema reduction and improved symptomatology (pain, a feeling of swelling of the upper limb, functional limitation, and patient dissatisfaction towards their body image. Following this analysis, one can conclude that the association of manual lymphatic drainage to physical exercise and physiotherapy has produced changes in the volume of the limb affected by the lymphedema; however, its isolated use has not resulted in significant changes.

Studies have shown that the association between exposure and disease can differ according to participants' beliefs or knowledge about the effect of that exposure on disease. We investigated the association between belief about breast cancer causation and self-reported shift work exposure in a case-control study. Women completed a questionnaire asking whether they believed that shift work caused cancer either before or after reporting their history of shift work. We measured: whether belief modified the association between reported shift work and disease; whether belief was associated with reported shift work exposure; and whether being prompted to recall shift work exposure was associated with an increased likelihood of believing that shift work increased breast cancer risk. There was a significant association between believing shift work increased breast cancer risk and reporting exposure to shift work. Being prompted to recall shift work was not associated with a belief that shift work increased risk. The association between pre-existing belief about breast cancer risk and reported shift work is likely to be due to exposed individuals believing that exposure increases risk, rather than resulting from recall bias.

    The aim of this study was to investigate whether a breast cancer diagnosis, personal assertiveness (i.e. frequency of assertive behaviour and tension associated with this behaviour), and partners' relationship-focused coping (i.e. active engagement and protective buffering) were sources of variation in patients' relationship satisfaction, cross-sectionally and over time. This longitudinal case-control study assessed the two dimensions of personal assertiveness and relationship satisfaction in both women with cancer (N=72) and comparison controls (N=62). In addition, patients completed a measure assessing their partners' active engagement and protective buffering. Cases (i.e. women with breast cancer) were not found to report more relationship problems than controls. Women with breast cancer who tended not to express their concerns and feelings and who experienced much tension when they did, reported relatively low marital satisfaction. Moreover, partners' protective buffering was associated with less relationship satisfaction in especially more assertive (i.e. high frequency of assertive behaviour and low tension) women with cancer, while active engagement was associated with more relationship satisfaction, regardless of the women's personal assertiveness. The results of the present study indicate that a breast cancer diagnosis by itself may not be a risk factor for relationship problems. However, in the context of an illness such as cancer, personal assertiveness, and a partner's relationship-focused coping strategies do seem to play a role in maintaining a satisfactory relationship with one's partner.

    We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (P(trend) = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (P(trend) = 0.005) but not cases (P(trend) = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (P(het) = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (OR(het) = 0.84, 95% CI 0.75, 0.94; OR(hom) = 0.81, 95% CI 0.51, 1.30; P(trend) = 0.002) but not for those who had their menarche age ≤11 years (OR(het) = 1.06, 95% CI 0.95, 1.19, OR(hom) = 1.07, 95% CI 0.67, 1.72; P(trend) = 0.29). To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between later age at menarche and a reduction in

    Vitamin D serum levels have been found to be related to sun exposure and diet, together with cell differentiation, growth control and consequently, cancer risk. Vitamin D receptor (VDR) genotypes may influence cancer risk; however, no epidemiological studies in sporadic breast cancer (BC) or malignant melanoma (MM) have been performed in a southern European population. In this study, the VDR gene has been evaluated in two epithelial cancers BC and MM. We have conducted an analysis in 549 consecutive and non-related sporadic BC cases and 556 controls, all from the Spanish population, and 283 MM cases and 245 controls. Genotyping analyses were carried out on four putatively functional SNPs within the VDR gene. An association with the minor allele A of the non-synonymous SNP rs2228570 (rs10735810, FokI, Met1Thr) was observed for BC, with an estimated odds ratio (OR) of 1.26 (95% CI = 1.02–1.57; p = 0.036). The synonymous variant rs731236 (TaqI) appeared to be associated with protection from BC (OR = 0.80, 95%CI = 0.64–0.99; p = 0.047). No statistically significant associations with MM were observed for any SNP. Nevertheless, sub-group analyses revealed an association between rs2228570 (FokI) and absence of childhood sunburns (OR = 0.65, p = 0.003), between the 3'utr SNP rs739837 (BglI) and fair skin (OR = 1.31, p = 0.048), and between the promoter SNP rs4516035 and the more aggressive tumour location in head-neck and trunk (OR = 1.54, p = 0.020). In summary, we observed associations between SNPs in the VDR gene and BC risk, and a comprehensive analysis using clinical and tumour characteristics as outcome variables has revealed potential associations with MM. These associations required confirmation in independent studies

    Phytoestrogens are structurally similar to estrogens and may affect breast cancer risk by mimicking estrogenic/antiestrogenic properties. In Western societies, whole grains and possibly soy foods are rich sources of phytoestrogens. A population-based case-control study in German postmenopausal women was used to evaluate the association of phytoestrogen-rich foods and dietary lignans with breast cancer risk. Dietary data were collected from 2,884 cases and 5,509 controls using a validated food-frequency questionnaire, which included additional questions phytoestrogen-rich foods. Associations were assessed using conditional logistic regression. All analyses were adjusted for relevant risk and confounding factors. Polytomous logistic regression analysis was performed to evaluate the associations by estrogen receptor (ER) status. High and low consumption of soybeans as well as of sunflower and pumpkin seeds were associated with significantly reduced breast cancer risk compared to no consumption (OR = 0.83, 95% CI = 0.70-0.97; and OR = 0.66, 95% CI = 0.77-0.97, respectively). The observed associations were not differential by ER status. No statistically significant associations were found for dietary intake of plant lignans, fiber, or the calculated enterolignans. Our results provide evidence for a reduced postmenopausal breast cancer risk associated with increased consumption of sunflower and pumpkin seeds and soybeans.

    Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by G?d?leanu and Craciun in 1987, and 48 cases have since been reported. The present study reports a case of synchronous bilateral breast oncocytic carcinoma. The patient was a 78-year-ol...

    Full Text Available Experimental data suggest a protective effect of vitamin D on breast cancer; however, epidemiologic results remain inclusive. With a Chinese population-based case-control study and meta-analysis of the observational studies, we here systematically evaluated the association of blood 25(OHD level and breast cancer risk. With 593 breast cancer cases and 580 cancer-free controls from Shanghai, China, we found that 80% of the normal women had severe vitamin D deficiency (less than 20 ng/mL and 15.2% had mild deficiency (20 to 30 ng/mL and only 4.8% of women had sufficient vitamin D level (>30 ng/mL while the proportion was 96.1%, 3.2% and 0.7% respectively for the breast cancer patients. Compared to those with the lowest quartile of plasma 25(OHD level, women with highest quartile 25(OHD level showed a significant decreased breast cancer risk (Q4 vs.Q1: OR = 0.10, 95% CI = 0.06-0.15 and every 1 ng/ml increment of plasma 25(OHD level led to a 16% lower odds of breast cancer (OR = 0.84, 95% CI = 0.81-0.87; P<0.001. From the meta-analysis of the observational studies, we found that women with highest quantile of blood 25(OHD level was associated with a significantly reduced breast cancer risk compared to those with lowest quantile of blood 25(OHD level for the 11 nested case-control and retrospective studies (pooled OR = 0.86, 95% CI = 0.75-1.00 and 10 case-control studies (7 population based, OR = 0.35, 95% CI = 0.24-0.52; 3 hospital based, OR = 0.08, 95% CI = 0.02-0.33. These results suggest that vitamin D may have a chemo-preventive effect against breast cancer.

    Purpose Despite the overlap between the clinical symptoms/sequelae of polycystic ovarian syndrome (PCOS) and many known reproductive risk factors for breast cancer, the relationship between PCOS and breast cancer remains unclear, possibly because of the complex heterogeneity and challenges in diagnosing PCOS over time. We hypothesized that PCOS, specific PCOS-related symptoms/sequelae, or clusters of PCOS-related symptoms/sequelae, may be differentially associated with pre- vs. postmenopausal breast cancer risk. Materials and Methods Cases were 1,508 women newly diagnosed with a first primary in situ or invasive breast, and the 1,556 population-based controls were frequency-matched by age. Results History of physician-diagnosed PCOS was reported by 2.2% (n=67), among whom oral contraceptive (OC) use, irregular menstruation, and infertility due to ovulatory dysfunction were common. Using unconditional logistic regression, adjusted odds ratios (95% confidence intervals) for PCOS were increased for premenopausal [2.74 (1.13, 6.63)], but not post-menopausal breast cancer [0.87 (0.44, 1.71)]. We used cluster analysis to investigate whether risk among all women varied by PCOS-related symptoms/sequelae, such as reproductive irregularities, OC use, and components of insulin resistance. In the cluster analysis, odds ratios were elevated among premenopausal women who had a history of OC use and no ovulatory dysfunction [1.39 (1.03, 1.88)], compared to those with fewer number of PCOS-related symptoms/sequelae. Conclusion PCOS, and associated PCOS-related symptoms/sequelae including OC use, may play a role in the development of premenopausal breast cancer. Our findings require confirmation in studies with a larger number of premenopausal women with systematically applied diagnostic criteria for PCOS. PMID:26797454

    Introduction: Breast cancer is the most common malignancy of the female population, the incidence is increasing mainly statistically between 50. a 60s, 60s and 70s. Recently, however, we meet more often with the occurrence of breast cancer in women in 30 year and significantly between 30 and 40 year. Cases: The following are examples of four young women who had different symptoms who failed primary diagnosis was revalued the importance of sonography and age, did not think the possibility of the presence of cancer. Results: The patients presented were finally correctly diagnosed, treated with a relatively good prognosis. Their diagnosis, however, could be faster and smaller tumors. However, despite the fact that Slovakia has enacted preventive investigation of the breast young women from the 20 to 40th of clinically and sonographically, encountered in practice, often with cases of breast cancer diagnosed late. Conclusion: Case report we highlight the diversity of clinical symptoms and the possibility of imaging diagnostic techniques in the diagnosis of breast disease of young women. We also want to draw attention to some underestimation of clinical symptoms, while revaluation results of sonographic examinations. An important factor is the quality of the ultrasound device and effective consultation and cooperation with other diagnostic departments. (author)

    Previous studies suggest that polycyclic aromatic hydrocarbons (PAHs) may adversely affect breast cancer risk. Indoor air pollution from use of indoor stoves and/or fireplaces is an important source of ambient PAH exposure. However, the association between indoor stove/fireplace use and breast cancer risk is unknown. We hypothesized that indoor stove/fireplace use in a Long Island, New York study population would be positively associated with breast cancer and differ by material burned, and the duration and timing of exposure. We also hypothesized that the association would vary by breast cancer subtype defined by p53 mutation status, and interact with glutathione S-transferases GSTM1, T1, A1 and P1 polymorphisms. Population-based, case-control resources (1,508 cases/1,556 controls) were used to conduct unconditional logistic regression to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Breast cancer risk was increased among women reporting ever burning synthetic logs (which may also contain wood) in their homes (OR = 1.42, 95% CI 1.11, 1.84), but not for ever burning wood alone (OR = 0.93, 95% CI 0.77, 1.12). For synthetic log use, longer duration >7 years, older age at exposure (>20 years; OR = 1.65, 95% CI 1.02, 2.67) and 2 or more variants in GSTM1, T1, A1 or P1 (OR = 1.71, 95% CI 1.09, 2.69) were associated with increased risk. Burning wood or synthetic logs are both indoor PAH exposure sources; however, positive associations were only observed for burning synthetic logs, which was stronger for longer exposures, adult exposures, and those with multiple GST variant genotypes. Therefore, our results should be interpreted with care and require replication.

    The development of breast cancer is multifactorial. Hormonal, environmental factors and genetic predisposition, among others, could interact in the presentation of breast carcinoma. Human leukocyte antigen (HLA) alleles play an important role in immunity (cellular immunity) and may be important genetic traits. HLAAllele-specific interaction has not been well established. Recently, several studies had been conducted in order to do so, but the results are controversial and in some instances contradictory. We designed a case-control study to quantify the association of HLA class I and II genes and breast cancer. HLA typing was performed by high resolution sequence-specific oligotyping after DNA amplification (PCR-SSOP) of 100 breast cancer Mexican mestizo patients and 99 matched healthy controls. HLA-A frequencies that we were able to observe that there was no difference between both groups from the statistical viewpoint. HLA-B*1501 was found three times more common in the case group (OR, 3.714; p = 0.031). HLA-Cw is not a marker neither for risk, nor protection for the disease, because we did not find significant statistical differences between the two groups. DRB1*1301, which is expressed in seven cases and in only one control, observing an risk increase of up to seven times and DRB1*1602, which behaves similarly in being present solely in the cases (OR, 16.701; 95% CI, 0.947 – 294.670). DQ*0301-allele expression, which is much more common in the control group and could be protective for the presentation of the disease (OR, 0.078; 95% CI, 0.027–0.223, p = 0.00001). Our results reveal the role of the MHC genes in the pathophysiology of breast cancer, suggesting that in the development of breast cancer exists a disorder of immune regulation. The triggering factor seems to be restricted to certain ethnic groups and certain geographical regions since the relevant MHC alleles are highly diverse. This is the first study in Mexican population where high resolutions HLA

    Breast cancer (BC) is a highly heterogeneous disease associated with metabolic reprogramming. The shifts in the metabolome caused by BC still lack data from Latin populations of Hispanic origin. In this pilot study, metabolomic and lipidomic approaches were performed to establish a plasma metabolic fingerprint of Colombian Hispanic women with BC. Data from 1H-NMR, GC-MS and LC-MS were combined and compared. Statistics showed discrimination between breast cancer and healthy subjects on all analytical platforms. The differentiating metabolites were involved in glycerolipid, glycerophospholipid, amino acid and fatty acid metabolism. This study demonstrates the usefulness of multiplatform approaches in metabolic/lipid fingerprinting studies to broaden the outlook of possible shifts in metabolism. Our findings propose relevant plasma metabolites that could contribute to a better understanding of underlying metabolic shifts driven by BC in women of Colombian Hispanic origin. Particularly, the understanding of the up-regulation of long chain fatty acyl carnitines and the down-regulation of cyclic phosphatidic acid (cPA). In addition, the mapped metabolic signatures in breast cancer were similar but not identical to those reported for non-Hispanic women, despite racial differences.

    Full Text Available Purpose. To study the distribution of breast mammogram density in Lebanese women and correlate it with breast cancer (BC incidence. Methods. Data from 1,049 women who had screening or diagnostic mammography were retrospectively reviewed. Age, menopausal status, contraceptives or hormonal replacement therapy (HRT, parity, breastfeeding, history of BC, breast mammogram density, and final BI-RADS assessment were collected. Breast density was analyzed in each age category and compared according to factors that could influence breast density and BC incidence. Results. 120 (11.4% patients had BC personal history with radiation and/or chemotherapy; 66 patients were postmenopausal under HRT. Mean age was 52.58±11.90 years. 76.4% of the patients (30–39 years had dense breasts. Parity, age, and menopausal status were correlated to breast density whereas breastfeeding and personal/family history of BC and HRT were not. In multivariate analysis, it was shown that the risk of breast cancer significantly increases 3.3% with age (P=0.005, 2.5 times in case of menopause (P=0.004, and 1.4 times when breast density increases (P=0.014. Conclusion. Breast density distribution in Lebanon is similar to the western society. Similarly to other studies, it was shown that high breast density was statistically related to breast cancer, especially in older and menopausal women.

    Purpose: The IGF-1R is a glycoprotein receptor that consists of a heterodimer of two alpha and two beta subunits which are processed from a single precursor transmembrane polypeptide and has been found to be overexpressed in a variety of tumors. IGF-1R has been shown to play a critical role in malignant transformation and to influence apoptosis. We have recently shown in gene transfer studies that overexpression of the IGF-1R confers relative radioresistance on mouse fibroblasts in culture. To test the significance of this finding in a clinical setting, we have sought to determine the prognostic significance of overexpression of IGF-1R with respect to ipsilateral breast tumor recurrence (IBTR) in the conservatively treated breast cancer patient. Materials and Methods: Over 1,000 breast cancer patients treated with conservative surgery followed by radiation therapy to the intact breast served as the patient population for this study. Twenty-five patients with a diagnosis of invasive ductal carcinoma who had an IBTR as the first site of failure comprised the index case population base of this study. Following the identification of 25 patients with IBTR, the breast database was searched for 25 matching control patients who did not have an IBTR. The control patients were matched to the index case with respect to age (within 5 years), menopausal status, approximate date of radiation therapy, primary histology, axillary dissection, nodal status, primary tumor size, estrogen/progesterone receptor (ER/PR) status, and adjuvant chemotherapy/hormonal therapy. Both index cases and the matched control group received radiation therapy to a total dose of 64 Gy to the tumor bed. Following identification of index and control cases, the individual paraffin-embedded blocks (PEB) were evaluated for invasive ductal carcinoma with H and E staining by the pathologist. All PEB were then processed for immunohistochemical staining with a polyclonal antibody to the beta-chain of IGF-1R

    Full Text Available A study of polychlorinated dibenzo-p-dioxins (PCDDs, polychlorinated dibenzofurans (PCDFs and polychlorinated biphenyls (dl-PCBs was conducted in a pooled sample of breast milk from 27 primiparous mothers living in 12 locations in the meso-region industrial area of southern Rio de Janeiro, Brazil, between August 2012 and July 2013. Questionnaires with questions regarding food habits, social and economic conditions and places of dwelling were applied. Milk was collected between four and six weeks after delivery from mothers were breast-feeding only one infant. The toxic equivalency (TEQ of PCDD/Fs, and dl-PCBs were 10.6, 4.77, 6.96 TEQ pg/g, respectively. The understanding and identification of pollution sources may be helpful for applying better counter measures against breast milk dioxin contamination. It is important for pregnant women to have a diet that is as free as possible from chemical contaminants. Further research must be undertaken in the context of epidemiological investigations to more accurately assess the effects of these compounds. The background contamination by PCDD/Fs, and dl-PCBs in mothers living at industrial area in Rio de Janeiro is lower than that generally found in industrialized countries.

    This multicenter prospective study aimed to assess the utility of dynamic enhanced magnetic resonance imaging (MRI) prior to breast-conserving surgery for breast cancer. The research subjects were drawn from patients with primary early resectable breast cancer treated in the breast disease centers of six three-level hospitals in Beijing from 1 January 2010 to 31 December 2012. The participants were allocated to a breast-conserving surgery group (breast-conserving group) or a total mastectomy group (total mastectomy group). Enhanced MRI was used to measure breast volume, longest diameter of tumor and tumor volume. The correlations between these measurements and those derived from histopathologic findings were assessed. The relationships between the success rate of breast-conserving surgery and MRI- and pathology-based measurement results were statistically analyzed in the breast-conserving group. The study included 461 cases in the total mastectomy group and 195 in the breast-conserving group. Allocation to these groups was based on clinical indications and patient preferences. The cut-off for concurrence between MRI- and pathology-based measurements of the longest diameter of tumor was set at 0.3 cm. In the total mastectomy group, the confidence interval for 95% concurrence of these measurements was 35.41%-44.63%. Correlation coefficients for MRI and histopathology-based measurements of breast volume, tumor volume and tumor volume/breast volume ratio were r = 0.861, 0.569, and 0.600, respectively (all P surgery were 100% and 88.54%, respectively. There were significant correlations between dynamic enhanced MRI- and histopathology-based measurements of the longest diameter of breast lesions, breast and tumor volumes, and breast volume/tumor volume ratios. Preoperative MRI examination improves the success rate of breast-conserving surgery.

  18. Polysomy of chromosome 17 in breast cancer tumors showing an overexpression of ERBB2: a study of 175 cases using fluorescence in situ hybridization and immunohistochemistry

    One of the most common genetic aberrations associated with breast cancer is the amplification and overexpression of the ERBB2 proto-oncogene located at chromosome 17, bands q12-21. The amplification/overexpression occurs in 25 to 30% of all breast cancers. In breast cancer, aneusomy of chromosome 17, either monosomy or polysomy, is frequently observed by conventional cytogenetics and fluorescence in situ hybridization (FISH). The aim of this study was to discover whether or not numerical aberrations on chromosome 17 have a correlation to the amplification or overexpression of the ERBB2 gene and to analyze their clinical implications in subgroups showing 2+ or 3+ positive scores by immunohistochemistry (IHC). We used FISH on a series of 175 formalin-fixed paraffin-embedded breast carcinomas to detect ERBB2 amplification, using a dual-probe system for the simultaneous enumeration of the ERBB2 gene and the centromeric region of chromosome 17, as well as using IHC to detect overexpression. We analyzed clinical and pathological variables in a subgroup of patients with 2+ and 3+ IHC scores (147 patients), to describe any differences in clinicopathological characteristics between polysomic and non-polysomic cases with the use of the χ 2 test. We found 13% of cases presenting polysomy, and three cases presented monosomy 17 (2%). According to the status of the ERBB2 gene, instances of polysomy 17 were more frequently observed in non-amplified cases than in FISH-amplified cases, suggesting that the mechanism for ERBB2 amplification is independent of polysomy 17. Polysomy 17 was detected in patients with 2+ and 3+ IHC scores. We found that nodal involvement was more frequent in polysomic than in non-polysomic cases (P = 0.046). The determination of the copy number of chromosome 17 should be incorporated into the assesment of ERBB2 status. It might also be helpful to differentiate a subgroup of breast cancer patients with polysomy of chromosome 17 and overexpression of ERBB2

    Fibroadenomatoid hyperplasia of the breast (FAHB) is a rare benign breast lesion and its clinical features are similar to fibroadenoma and fibrocystic changes. FAHB has been previously termed sclerosing lobular hyperplasia, fibroadenomatosis, fibroadenomatoid change, or fibroadenomatoid mastopathy. Typically, FAHB is derived from stroma and epithelia. The pathologic characteristics of FAHB are microfocal lobulocentric proliferation of stroma accompanied by epithelial and myoepithelial components resembling similar histological changes, as found in fibroadenoma, apocrine hyperplasia, intraductal hyperplasia, and lobular hyperplasia. FAHB could be present as a localized or diffused pattern in pathology. Most cases show no well-circumscribed mass lesions and no apparent capsules; it is usually identified as an incidental finding in other benign lesions or in random sampling in cancerous breast tissues. FAHB is categorized as a benign proliferative breast disease and it has previously been reported; however, the authors believe this study may be the first case with two giant masses reported. Fiber adenoma hyperplasia is a rare cystic hyperplasia of breast pathology and its ultrasonographic manifestations are easily confused with breast cancer. Comparative MRI ultrasound analysis will help make the differential diagnosis. © 2014 S. Karger AG, Basel.

    The aim of this study was to examine breast density in relation to breast cancer specific survival and to assess if this potential association was modified by mode of detection. An additional aim was to study whether the established association between mode of detection and survival is modified by breast density. The study included 619 cases from a prospective cohort, The Malmö Diet and Cancer Study. Breast density estimated qualitatively, was analyzed in relation to breast cancer death, in non-symptomatic and symptomatic women, using Cox regression calculating hazard ratios (HR) with 95% confidence intervals. Adjustments were made in several steps for; diagnostic age, tumour size, axillary lymph node involvement, grade, hormone receptor status, body mass index (baseline), diagnostic period, use of hormone replacement therapy at diagnosis and mode of detection. Detection mode in relation to survival was analyzed stratified for breast density. Differences in HR following different adjustments were analyzed by Freedmans%. After adjustment for age and other prognostic factors, women with dense, as compared to fatty breasts, had an increased risk of breast cancer death, HR 2.56:1.07-6.11, with a statistically significant trend over density categories, p = 0.04. In the stratified analysis, the effect was less pronounced in non-symptomatic women, HR 2.04:0.49-8.49 as compared to symptomatic, HR 3.40:1.06-10.90. In the unadjusted model, symptomatic women had a higher risk of breast cancer death, regardless of breast density. Analyzed by Freedmans%, age, tumour size, lymph nodes, grade, diagnostic period, ER and PgR explained 55.5% of the observed differences in mortality between non-symptomatic and symptomatic cases. Additional adjustment for breast density caused only a minor change. High breast density at diagnosis may be associated with decreased breast cancer survival. This association appears to be stronger in women with symptomatic cancers but breast density could

    Full Text Available Background: The main function of the pineal hormone melatonin which is mediated via its two receptors, MTNR1A and MTNR1B, is to mediate dark signals in addition to anti-oxidation, immune system enhancement, protection from radiation, and anti-cancer functions. A common single nucleotide polymorphism in the MTNR1B gene is rs#10830963, which is well known as a risk factor for type 2 diabetes mellitus. This study intends to figure out the role of melatonin and its receptor MTNR1B gene rs#10830963 polymorphism in breast cancer incidence, diagnosis and prognosis. Methods: This study included 43 females with breast cancer and 45 apparently normal healthy females. Restriction fragment length polymorphism-PCR was used for amplification and genotyping of the MTNR1B gene rs#10830963 polymorphism in whole blood. Serum melatonin levels were measured using a ready-for-use radioimmunoassay kit. Results: For the MTNR1B gene rs#10830963 polymorphism, we observed a significantly higher GG genotype frequency among cases (72.1% than controls (13.3%, with a diagnostic sensitivity of 83.78% and specificity of 76.47%. The cases had a frequency of 11.6% for the CC genotype and 16.3% for the CG genotype which was significantly lower compared to controls that had a 44.4% frequency of the CC genotype and 42.2% frequency of the CG genotype. The GG genotype had a significant association with larger tumor volume (P=0.048. Serum melatonin levels were significantly lower among breast cancer patients than controls. Using the ROC curve analysis, serum melatonin showed a significant AUC (72.6%, P39.5 pg/ml. Conclusion: The risk for breast cancer incidence increased as the serum levels of melatonin decreased and in females homozygous for the G allele (GG genotype of the MTNR1B gene rs#10830963 polymorphism. The GG genotype was found to be associated with increased breast tumor volume as a marker of a poor prognosis breast cancer.

    Full Text Available Abstract Background Squamous cells are normally not found inside the breast, so a primary squamous cell carcinoma of the breast is an exceptional phenomenon. There is a possible explanation for these findings. Case presentation A 72-year-old woman presented with a breast abnormality suspected for breast carcinoma. After the operation the pathological examination revealed a primary squamous cell carcinoma of the breast. Conclusion The presentation of squamous cell carcinoma could be similar to that of an adenocarcinoma. However, a squamous cell carcinoma of the breast could also develop from a complicated breast cyst or abscess. Therefore, pathological examination of these apparent benign abnormalities is mandatory.

    Identify the current physical and mental health status and health behaviors of male breast cancer survivors. Using data from the national, population-based, 2009 Behavioral Risk Factor Surveillance System (BRFSS) survey, 66 cases of male breast cancer were identified (mean age = 66.2 years, mean time since diagnosis = 12.0 years). Male breast cancer cases were matched with 198 male BRFSS respondents with no history of cancer (control group) on age, education, and minority status. The male breast cancer and control groups were compared on physical and mental health status and health behaviors, using t-test and logistic regression analyses. The male breast cancer group reported poorer physical and mental health than controls. Male breast cancer survivors were significantly (p mental health (Effect Size = 0.49), and physical health (Effect Size = 0.29) were not good. In contrast, the male breast cancer and control groups were similar with regard to current health behaviors, including tobacco and alcohol use, diet, exercise, and health care. The diagnosis and treatment of male breast cancer may be associated with clinically important and long-term deficits in physical and mental health status, deficits which may exceed those evidenced by long-term female breast cancer survivors.

    Lung cancer in men and breast cancer in women are the most commonly diagnosed cancers in Poland and worldwide. Results of studies involving dietary patterns (DPs) and breast or lung cancer risk in European countries outside the Mediterranean Sea region are limited and inconclusive. This study aimed to develop a 'Polish-adapted Mediterranean Diet' ('Polish-aMED') score, and then study the associations between the 'Polish-aMED' score and a posteriori -derived dietary patterns with breast or lung cancer risk in adult Poles. This pooled analysis of two case-control studies involved 560 subjects (280 men, 280 women) aged 40-75 years from Northeastern Poland. Diagnoses of breast cancer in 140 women and lung cancer in 140 men were found. The food frequency consumption of 21 selected food groups was collected using a 62-item Food Frequency Questionnaire (FFQ)-6. The 'Polish-adapted Mediterranean Diet' score which included eight items-vegetables, fruit, whole grain, fish, legumes, nuts and seeds-as well as the ratio of vegetable oils to animal fat and red and processed meat was developed (range: 0-8 points). Three DPs were identified in a Principal Component Analysis: 'Prudent', 'Non-healthy', 'Dressings and sweetened-low-fat dairy'. In a multiple logistic regression analysis, two models were created: crude, and adjusted for age, sex, type of cancer, Body Mass Index (BMI), socioeconomic status (SES) index, overall physical activity, smoking status and alcohol abuse. The risk of breast or lung cancer was lower in the average (3-5 points) and high (6-8 points) levels of the 'Polish-aMED' score compared to the low (0-2 points) level by 51% (odds ratio (OR): 0.49; 95% confidence interval (Cl): 0.30-0.80; p Mediterranean diet could be considered for adults living in non-Mediterranean countries for the prevention of the breast or lung cancers. Future studies should explore the role of a traditional Mediterranean diet fitted to local dietary patterns of non-Mediterranean Europeans

    To report a rare presentation of necrotizing fasciitis (NF) in the breast and its management. A 61-year-old non-diabetic lady presented with a painful swollen right breast and yellowish discharge associated with fever for the last few days. Based on clinical examination and haematological parameters, a provisional diagnosis of breast abscess was made that later proved to be a case of NF. She was managed conservatively with repeated debridement followed by split-skin grafting with preservation of the breast. This case showed that NF of the breast can present as a simple breast abscess which was managed conservatively. Copyright © 2011 S. Karger AG, Basel.

    The popularity of cosmetic breast augmentation and the incidence of breast cancer have been increasing worldwide. It has been hypothesized that the risk of breast cancer may be greater among patients who have undergone cosmetic breast implantation. The authors performed a meta-analysis of the available literature on the risk of breast cancer among women with cosmetic breast implants. The study was designed as a meta-analysis of observational studies. A systematic search of the English literature (published by August 28, 2013) was conducted in PubMed and EMBASE. Eligible reports were those that included relative risk (RR; the increased or decreased risk of breast cancer associated with breast implants) or the standardized incidence ratio (SIR) of the observed number of cases of breast cancer to the expected number of cases among patients that previously underwent cosmetic breast augmentation. Seventeen studies representing 7 cohorts were selected. Some of these were follow-up reports of previously published studies; in such cases, only the most recent reports were included in the meta-analysis. Summary SIR and RR rates and the corresponding 95% confidence intervals (CIs) were calculated with a random-effects (SIR) or fixed-effects (RR) model. The overall SIR estimate was 0.69 (95% CI, 0.56-0.85), and the overall RR, based on 4 studies, was 0.63 (95% CI, 0.56-0.71). Finding of this meta-analysis suggest that women who have undergone cosmetic breast implantation do not have an increased risk of breast cancer. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Background: Gestational or pregnancy-associated breast cancer is defined as breast cancer diagnosed during pregnancy, within the first postpartum year, or during lactation. Breast cancer is one of the most common cancers in nonpregnant and pregnant women. Case presentation: A 29-year-old pregnant woman presented at eight weeks gestational age with a palpable breast nodule. On breast ultrasound evaluation, only probably benign findings were detected. The pregnancy was uneventful until the third trimester when she started to have a severe back pain which became gradually resistant to medical therapy. Therefore, at 33 weeks, she was assisted at an emergency care facility and a highly suspicious breast mass was detected. A core biopsy was performed that revealed an invasive ductal carcinoma grade 3 with lymph node metastasis. After several imaging studies, it was diagnosed as a stage 4 breast cancer with bone, liver, and pulmonary metastasis. At thirty four weeks gestation, the pregnancy was terminated by C-section and she started to receive palliative radiation therapy one week later. She also received several cycles of palliative chemotherapy. Nineteenth months after C-section, progression of the disease was observed and a cerebellar metastasis was found. Unfortunately, two months later, her clinical condition deteriorated and the patient died.Conclusion: Gestational breast cancer represents a clinical situation of utmost important in which the health of both the mother and the fetus should be taken into account. Diagnosis is difficult due to the physiological changes of the mammary glands during pregnancy and lactation, and it usually occurs at an advanced stage.

    Full Text Available Abstract Background A single nucleotide polymorphism located in the 3'-untranslated region of the KRAS oncogene (KRAS variant; rs61764370 disrupts a let-7 miRNA binding and was recently reported to act as a genetic marker for increased risk of developing human cancers. We aimed to investigate an association of the KRAS variant with sporadic and familial breast cancer and breast tumor characteristics. Methods Genotyping was accomplished in 530 sporadic postmenopausal breast cancer cases, 165 familial breast cancer cases (including N = 29, who test positive for BRCA1/2 mutations and 270 postmenopausal control women using the flurogenic 5' nuclease assay. Information on hormone replacement therapy (HRT use and tumor characteristics in sporadic breast cancer cases was ascertained from a postal questionnaire and pathology reports, respectively. Associations between the KRAS genotype and breast cancer or breast tumor characteristics were assessed using chi-square test and logistic regression models. Results No evidence of association was observed between the KRAS variant and risk of sporadic and familial breast cancer - either among BRCA carriers or non-BRCA carriers. The KRAS variant was statistically significantly more often associated with human epidermal growth factor receptor 2 (HER2 - positive tumors and tumors of higher histopathologic grade. However, both associations were detected only in HRT users. Conclusion Our data do not support the hypothesis that the KRAS variant rs61764370 is implicated in the aetiology of sporadic or of familial breast cancer. In postmenopausal women using HRT, the KRAS variant might lead to HER2 overexpressed and poorly-differentiated breast tumors, both indicators of a worse prognosis.

    The associations between emotional personality, proximity and authenticity in patient-physician communication during breast cancer (BC) consultations are rarely considered together in a prospective study. We, therefore, investigated emotional personality/proximity versus authenticity in patient-physician communication in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC). In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated regarding emotional personality, proximity and authenticity in their a patient-physician communication before any diagnostic procedures were carried-out. The emotional personality and the emotional proximity in patient-physician communication was highly significantly positively correlated in the BBD group. The kappa-values for emotional personality versus emotional proximity in the HSS, BBD and BC groups were statistically significant. There was also a highly significant positive correlation between emotional personality and emotional authenticity in the HSS, BBD and BC groups and the kappa values in the HSS, BBD and BC groups were statistically significant. There was a highly significant positive correlation between emotional proximity and emotional authenticity in the BBD group, and the weighted kappa-values in the BBD group were statistically significant. The results of the present study support a powerful link between emotional personality/proximity and emotional authenticity, and provides new information in patient-physician communication in the HSS, BBD and BC groups. This finding is of clinical importance, since during breast disease consultation, barriers to patient-physician communication may be associated with difficulties in early BC diagnosis in the breast cancer diagnostic unit.

    Psychosocial factors have been linked to the development and progression of cancer and shown to be relevant in cancer care. However, the evidence that psychosocial interventions affect cancer survival is less conclusive. Few methodologically sound studies have addressed this issue. To investigate the effects of a 6-week psychosocial intervention on survival among patients with stage I breast and prostate cancer. Matched case-control. 3 rural hospitals or cancer centers in central Pennsylvania. 21 breast and 29 prostate stage I cancer patients (treatment group) matched with 74 breast and 65 prostate stage I cancer patients from the same hospitals who did not receive the intervention (control group). Six 2-hour health psychology classes conducted by a licensed staff psychologist. Survival time was compared between the 2 groups and with national norms. The intervention group lived significantly longer than did matched controls. At 4- to 7-year follow-up (median = 4.2 years), none of the breast cancer patients in the intervention group died, whereas 12% of those in the control group died. Twice as many matched-control prostate cancer patients died compared with those in the intervention group (28% vs 14%). Control group survival was similar to national norms. These results are consistent with prior clinical trials and suggest that short-term psychosocial interventions that encourage the expression of emotions, provide social support, and teach coping skills can influence survival among cancer patients. However, self-selection bias cannot be ruled out as an alternative explanation for the results. These interventions merit further consideration and research.

    Full Text Available Invasive papillary carcinoma of the breast is a rare, distinct variant comprising approximately less than 1-2% of all newly diagnosed cases of breast carcinoma and is usually found in postmenopausal women with a more favorable prognosis. We report an unusual case in a 45-year-old perimenopausal female who came with a complaint of lump in right breast for duration of 1 year. A simple mastectomy was undertaken for histopathological study and immunohistochemistry (IHC which showed characteristic features of an invasive papillary breast carcinoma. We present this case in view of its rarity and to highlight this clinicopathological subtype for its good prognosis and to avoid overtreatment.

    Full Text Available Most breast masses arise from the breast. Metastasis to the breast is fairly uncommon, but can occur in breast skin and parenchyma. In particular, leukemia and lung cancers, and MM may metastasize to the breast. Breast metastasis might be the first symptom or may occur during the course of other malignancies. Our case presented with a fixed mass in the upper-medial quadrant of her left breast during regular follow-up visits. The mean time to breast metastasis in patients with MM is 62 months (13-178. In our case this time was 48 months. In a case series with 7 patients hematological malignancies (Hodgkin lymphoma, non-Hodgkin lymphoma, and leukemia were the leading cause of breast metastasis, whereas in only 1 case the cause was MM. In another case series of 15 MM patients with metastasis to the breast, the primary tumor was frequently localized to the upper extremities and trunk. In a report of 250 conjunctival MM cases the mortality rate was significantly higher in patients with tumors >4 mm in vertical thickness. In another 45-case MM series tumors with a diameter >10 mm were associated with higher mortality rates. In our case the thickness of the tumor was 5 mm. In conclusion, histopathological evaluation should be mandatory in patients with known primary malignancies in order to differentiate new primary tumors, metastases, and benign tumors.

  19. Benign osseous metaplasia of the breast: Case report

    Hassan Alyami

    Full Text Available Introduction: Benign Osseous metaplasia of the breast is rare, with only a few cases reported in the literature. Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. Case presentation: 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified fibroadenoma. An ultrasound-guided true cut biopsy revealed fibrous tissue containing foci of adenosis in the presence of a myoepithelial cell layer. Excision biopsy was performed, and histopathological examination showed bone matrix deposition occupying most of the nodule with peripheral hyalinized tissue but no evidence of malignancy. A diagnosis of benign osseous metaplasia of the breast was made, and the patient recovered well without recurrence after lump excision. Discussion: Only a few cases of osseous metaplasia are reported in the literature. Most reported cases are malignant, such as in fibrosarcoma, malignant mesenchymoma, osteoid sarcoma, osteogenic sarcoma, and osteochondrosarcoma.Very few cases of osseous sarcoma are reported in benign lesions such as fibroadenoma, pleomorphic adenoma, benign mesenchymoma, phyllodes tumor, and amyloid tumor of the breast. Joshi et al. first reported a case of benign osseous metaplasia of the breast presenting as breast lump in an HIV-positive patient [18]. We, therefore, consider this case to be the second case report of benign osseous metaplasia of the breast presenting as a breast lump, but the patient had no chronic illness. Conclusion: A breast lump can be the first presentation of benign osseous metaplasia. Keywords: Benign osseous metaplasia, Breast lump, Case report

    Breast cancer is one of the commonest cancers diagnosed among women around the world. Simulation approach has been utilized to study, characterize and improvise detection methods for breast cancer. However, minimal simulation work has been done to evaluate the surface stress of the breast with lumps. Thus, in this work, simulation analysis was utilized to evaluate and assess the breast surface stress due to the presence of a lump within the internal structure of the breast. The simulation was conducted using the Elmer software. Simulation results have confirmed that the presence of a lump within the breast causes stress on the skin surface of the breast.

    Male breast cancer is very rare, with the incidence of 0.15-1% of all breast cancers and less than 1% of all cancers in men. The prognosis of male breast cancer is poorer than that of female because the median age of detection of the disease is in more late stage. It usually involves higher axillary lymph nodes. We report two case of male breast cancer to describe characteristic mammographic and ultrasonographic findings and to compare with the findings of gynaecomastia.

    2007-11-15

    Background: The Icelandic breast cancer screening program, initiated November 1987 in Reykjavik and covering the whole country from December 1989, comprises biennial invitation to mammography for women aged 40-69 years old. Purpose: To estimate the impact of mammography service screening in Iceland on deaths from breast cancer. Material and Methods: Cases were deaths from breast cancer from 1990 onwards in women aged 40 and over at diagnosis, during the period November 1987 to December 31, 2002. Age- and screening-area-matched, population-based controls were women who had also been invited to screening but were alive at the time their case died. Results: Using conditional logistic regression on the data from 226 cases and 902 controls, the odds ratio for the risk of death from breast cancer in those attending at least one screen compared to those never screened was 0.59 (95% CI 0.41-0.84). After adjustment for healthy-volunteer bias and screening-opportunity bias, the odds ratio was 0.65 (95% CI 0.39-1.09). Conclusion: These results indicate a 35-40% reduction in breast cancer deaths by attending the Icelandic breast cancer screening program. These results are consistent with the overall evidence from other observational evaluations of mammography-based programs.

    Genetic determinants of breast cancer (BC) remained largely unknown in the majority of Moroccan patients. The purpose of this study was to explore the association of ERCC2 and MTHFR polymorphisms with genetic susceptibility to breast cancer in Moroccan population. We genotyped ERCC2 polymorphisms (rs1799793 (G934A) and rs13181 (A2251C)) and MTHFR polymorphisms (rs1801133 (C677T) and rs1801131 (A1298C)) using TaqMan SNP Genotyping Assays. Genotypes were compared in 151 BC cases and 156 population-matched controls. Allelic, genotypic and haplotype associations with the risk and clinicopathological features of BC were assessed using logistic regression analyses. ERCC2-rs1799793-AA genotype was associated with high risk of BC compared to wild type genotype (recessive model: OR: 2.90, 95% CI: 1.34-6.26, p = 0.0069) even after Bonferroni correction (p < 0,0125). MTHFR rs1801133-TT genotype was associated with increased risk of BC (recessive model, OR: 2.49, 95% CI: 1.17-5.29, p = 0.017) but the association turned insignificant after Bonferroni correction. For the rest of SNPs, no statistical associations to BC risk were detected. Significant association with clinical features was detected for MTHFR-rs1801133-TC genotype with early age at diagnosis and familial BC. Following Bonferroni correction, only association with familial BC remained significant. MTHFR-rs1801131-CC genotype was associated with sporadic BC. ERCC2-rs1799793-AA genotype correlated with ER+ and PR+ breast cancer. ERCC2-rs13181-CA genotype was significantly associated large tumors (T ≥ 3) in BC patients. None of these associations passed Bonferroni correction. Haplotype analysis showed that ERCC2 A-C haplotype was significantly associated with increased BC risk (OR: 3.71, 95% CI: 1.7-8.12, p = 0.0002 and p = 0.0008 before and after Bonferroni correction, respectively) and positive expression of ER and PR in BC patients. ERCC2 G-C haplotype was correlated with PR negative and

    Introduction: Being diagnosed with breast cancer is devastating for women because they face a sense of loss. Since this loss is observed by the women themselves as well as by those around them, this can often lead to depression. Objectives: (1) To verify a possible association between body image and depression; (2) To establish a relation between depression and time since breast cancer diagnosis. Method: The data came from the Beck Depression Inventory (BDI-II) and the Body Image Scale (BIS),...

    The purpose of this study was to determine the impact of revised ASCO/CAP 2013 HER2 guidelines on the clinical practice of pathologists and oncologists. Retrospective analysis of 1739 patients with invasive breast carcinoma who underwent reflex HER2 (fluorescence in situ hybridization [FISH]) testing, using both 2007 and 2013 guidelines (2007-2014). Using 2013 guidelines, 255 (15%; 95% confidence interval [CI], 13%-16%) cases were classified as HER2 + as opposed to 186 (11%; 95% CI, 9%-12%) by 2007 guidelines (odds ratio [OR] 1.4; 95% CI, 1.2-1.8; P = .0005). Sixty-nine cases equivocal by 2007 guidelines (12% of all equivocal cases) were converted to HER2 + by 2013 guidelines. Sixty-two of these 69 cases shifted from HER2 equivocal to positive due to change in FISH ratio cutoff from 2.2 to 2.0. Six cases had FISH ratio guidelines. No increase in HER2 FISH equivocal cases was observed. Reflex FISH testing of all IHC 1+ cases at our institution additionally detected 58 patients (5%; 95% CI, 4%-6%) with HER2 amplification. The 2013 guidelines increase the detection of HER2 + cases, without introducing significant difference in discordance rate of the IHC and FISH assays. Inclusion of HER2 copy number criterion does not increase the number of FISH equivocal cases in our cohort. We recommend IHC 1+ cases should be offered reflex FISH testing because failure to test them will miss a small number (5%) of potentially treatable cases. Copyright © 2017 Elsevier Inc.

    2014-08-01

    Full Text Available OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, along with a literature review. METHOD: We reviewed the demographic data, pathologic analyses and imaging and results of patients diagnosed with breast hamartoma between December 2003 and September 2013. RESULTS: In total, 27 cases of breast hamartoma operated in the Ankara University Medicine Faculty's Department of General Surgery were included in the study. All patients were female and the mean age was 41.8±10.8 years. The mean tumor size was 3.9±2.7 cm. Breast ultrasound was performed on all patients before surgery. The most common additional lesion was epithelial hyperplasia (22.2%. Furthermore, lobular carcinoma in situ was identified in one case and invasive ductal carcinoma was observed in another case. Immunohistochemical staining revealed myoid hamartoma in one case (3.7%. CONCLUSION: Breast hamartomas are rare benign lesions that may be underdiagnosed because of the categorization of hamartomas as fibroadenomas by pathologists. Pathologic examinations can show variability from one case to another. Thus, the true incidence may be higher than the literature indicates.

    This is a report of the experience with 200 patients who during 1981 to 1984 underwent breast scanning on a conventional body scanner. Pre- and post-contrast scans of the breast were obtained. A postcontrast enhancement of 50 HU and more turned out to be specific for malignant lesions. Radiation dose to the breast was in the same range as with high filtration xeromammography and high resolution film-screen mammography with additional grid. Breast scanning is recommended in cases in which mammography alone is of limited value, including dense fibrocystic breasts in women at high risk, follow-up in breast cancer patients after breast conserving therapy, in patients with silastic implants and in the follow-up of breasts with huge scars due to multiple biopsies.

    Chemo- and radiotherapy are treatments very helpful to cure cancers but are also well known for adverse effects such as secondary cancers. Breast cancers following Hodgkin lymphoma have been relatively well studied. Breast cancers after radiotherapy covering or nearby breasts or nipples are usually carcinomas or secondary sarcomas. Among the big cohort of patients treated for breast carcinomas, breast lymphomas developed in the same area are not usual. Nevertheless, published studies described a significant increased risk of non-Hodgkin lymphoma after initial radiotherapy for a solid cancer. Here, we report a case of a secondary breast lymphoma observed in a 53-year-old woman treated 13 years before for a ductal carcinoma and analyse such second tumors with a review of the literature. This case report emphasizes the importance of the biopsy in case of recurrence in breast cancer to give the appropriate treatment.

    To assess dosimetric parameters in a case study where bilateral accelerated partial breast irradiation (APBI) is delivered using a strut-adjusted volume implant (SAVI) device. A 59-year-old female received APBI in both breasts over 5 days, with fractions of 3.4 Gy twice daily. A Vac-lok system was used for immobilization, and a C-arm was used for daily imaging. We generated dose-volume histograms (DVHs) for the brachytherapy plans to derive several important biologic factors. We calculated the normal tissue complication probability (NTCP), equivalent uniform dose (EUD), and tumor control probability (TCP) using the Lyman-Kutcher-Burman model parameters {alpha} = 0.3 Gy{sup -1}, {alpha}/{beta} = 4 Gy, n = 0.1, and m = 0.3. In addition, we assessed the dose homogeneity index (DHI), overdose index, and dose nonuniformity ratio. D95 was >95% and V150 was <50 mL for both breasts. The DHIs were 0.469 and 0.512 for the left and right breasts, respectively. The EUDs (normalized to 3.4 Gy b.i.d.) were 33.53 and 29.10 Gy. The TCPs were estimated at 99.2% and 99.9%, whereas the NTCP values were 4.2% and 2.57%. In this clinical case, we were able to quantify the dosimetric parameters of an APBI treatment performed with a SAVI device.

    A case of angiosarcoma of the left breast occurring one month after radiotherapy following partial mastectomy for a cancer of the right breast is described. A 43-year-old woman underwent right partial mastectomy and axillary lymphnode dissection for a right breast cancer on February 23, 1993. Radiation therapy (total 50 grey) was given to the right breast for 3 weeks postoperatively. A small hemangioma appeared near the nipple of her left breast in the following month. On June 23, we excised the grain sized hemangioma and diagnosed as angiosarcoma. After her hesitating several months, she underwent left mastectomy because of some relapses appeared around her left breast on January 20, 1994. Now she is doing well without recurrence. Angiosarcoma of the breast is extremely rare in our country and only 20 cases have been seen in the Japanese literature. This case of angiosarcoma of the breast which occurred after radiotherapy is the first report of Stewart-Treves syndrome. Recent increasing use of radiotherapy following breast-sparing operation may contribute to an increase in occurrence of angiosarcoma. We should strictly follow up irradiated patients with breast cancer entertaining possible occurrence of angiosarcoma of the breast as well as that of the upper extremities. (author)

    The purpose of the study was to compare two methods used to analyse HER-2 gene amplification (fluorescence in situ hybridisation (FISH) and chromogenic in situ hybridisation (CISH)), and determine the accuracy of the antibodies CB11 and HercepTest for immunohistochemical detection of HER-2 overexpression from archival breast cancer tissue. Additionally, interobserver variability in the interpretation of CISH and immunohistochemical tests was measured. Two hundred cases of invasive breast carcinoma diagnosed between 2000 and 2003 were selected. Immunohistochemistry (IHC) was performed with HercepTest and CB11, and gene amplification was determined by FISH (PathVision, Vysis) and CISH (Zymed) using tissue macroarrays. An excellent concordance (94.8%) was found between CISH and FISH. Considering FISH as gold standard, sensitivity of CISH was 97.5% and specificity 94%. Overall interobserver agreement of CISH was 97.5% and of IHC 84%. Both antibodies showed a sensitivity of 95.2% and a specificity of 70.7% (CB11) and 81.2% (HercepTest). Our results show that CISH is a highly accurate, reproducible and practical technique to determine HER-2 gene amplification. CB11 and HercepTest are good screening methods with a high sensitivity. The performance of tissue macroarrays to test HER-2 status by IHC, FISH and CISH has demonstrated to be an available and effective method to study large series of tumours.

    Recent genome-wide association study has identified a genetic variant rs4973768, located in 3'-UTR of solute carrier family 4, sodium bicarbonate cotransporter, member 7 (SLC4A7), was associated with increased risk of breast cancer (BC). However, several following replication studies cannot yield consistent results. We thus conducted a hospital-based case-control study including 485 patients and 514 controls, combined a meta-analysis including 108,632 cases and 135,818 controls to explore the relationship between this variant and BC risk. Our case-control study showed that rs4973768 was significantly associated with increased BC risk with the odds ratio (OR) of 1.29 (95 % confidence interval [CI]: 1.04-1.60) under the allelic model. In addition, the meta-analysis also indicated that the variant slightly increased the risk of BC with the pooled OR of the per-allele effect being 1.08 (95 % CI: 1.04-1.11) although with significant heterogeneity between studies. Stratified analyses showed that ethnicity, sample size, and study design may explain part of the heterogeneity. Moreover, the bioinformatics analysis suggested that this variant may influence the transcriptional capacity of SLC4A7. In summary, our results showed that the SLC4A7 variant, rs4973768, is associated with risk of BC although the underlying biologic mechanism warrants further studies.

    Full Text Available Fibro - adenoma typically occurs in fully developed breast between the ages of 20 and 35 years and generally it is uncommon to find palpable breast masses in young adolescent patients. We present a case of a 13 - year - old girl with a 20 × 20 cm, enlarging mass in left breast since three months, for whom resection and breast reduction was effectively achieved by total excision biopsy, preserving the nipple and areola. Fine - needle aspiration cytology showed a benign proliferative breast lesion. Histopathology revealed both intracanalicular and pericana licular component with predominant pericanalicular pattern of fibroadenoma

    To study the nutritional risk factors and status of serum 25(OH)D levels in patients with breast cancer. A total of 100 women (cases) with confirmed breast cancer (BC) matched with equal number of healthy females (controls) of similar age and socioeconomic status (SES) were included in study. Controls included were nonbreast cancer patients who accompanied the patients to a tertiary care hospital. All the subjects (cases and controls) were administered a questionnaires to collect data on socioeconomic status, dietary pattern and the frequency of food consumption using a validated food frequency questionnaire. Anthropometric assessment was done for waist and hip circumference to calculate waist to hip ratio (WHR). Non fasting blood samples were collected for serum 25-hydroxyvitamin D [25(OH)D] levels estimation using chemiluminescent immunoassay technique and total serum calcium levels by colorimetric assay technique. Serum 25(OH)D and total calcium levels were expressed in ng/ml and mg/dl. Vitamin D deficiency was defined as per the guidelines set by United States Endocrine Society. The mean age of cases and controls was 45±9 and 46±10 years respectively. On multivariate analysis, an inverse association with BC was found for less frequency of fruits consumption with an adjusted (ORs, 95% CI) (2.7, 0.5-15.7) respectively. Mushroom intake was inversely associated with risk of BC (ORs, 95% CI) (5.6, 1.9-16.6). Saturated fat intake and high WHR were significantly associated with high risk of BC with adjusted ORs, 95% CI of (3.4, 1.4-8.1) and (5, 1.4-17). A significant association (pnutritional risk factors determined by higher WHR was found to be significantly associated with the risk of BC. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Night work has been associated with risk of breast cancer but this association needs to be confirmed. Because breast cancer is an etiologically heterogeneous disease, we explored the association of night work with breast cancer subtypes defined by tumor status (positive of negative) for estrogen-receptor (ER), progesterone-receptor (PR) and human epidermal growth factor-receptor 2 (HER2). Using the data from a case-control study in France including 975 cases and 1317 controls, we found that the odds ratios for ER+, PR+ or HER2+ breast cancers subtypes were significantly elevated, while no association with night shift work was observed for ER, PR or HER2-negative tumors. After stratification by menopausal status, the associations of night work with receptor-positive breast tumor subtypes were clearly seen in premenopausal women (odds ratios 2.04, 1.98 and 2.80, respectively) but did not appear in postmenopausal women. This study provides evidence that working at night may increase risk of ER, PR and HER2-positive subtypes of breast cancer particularly among premenopausal women.

    The objective of our study was to assess, in a reader study, radiologists' performance in interpretation of automated breast volume scanner (ABVS) images with the aid of a computer-aided detection (CADe) system. Our study is a retrospective observer study with the purpose of investigating the effectiveness of using a CADe system as an aid for radiologists in interpretation of ABVS images. The multiple-reader, multiple-case study was designed to compare the diagnostic performance of radiologists with and without CADe. The study included 1000 cases selected from ABVS examinations in our institution in 2012. Among those cases were 206 malignant, 486 benign and 308 normal cases. The cancer cases were consecutive; the benign and normal cases were randomly selected. All malignant and benign cases were confirmed by biopsy or surgery, and normal cases were confirmed by 2-y follow-up. Reader performance was compared in terms of area under the receiver operating characteristic curve, sensitivity and specificity. Additionally, the reading time per case for each reader was recorded. Nine radiologists from our institution participated in the study. Three had more than 8 y of ultrasound experience and more than 4 y of ABVS experience (group A); 3 had more than 5 y of ultrasound experience (group B), and 3 had more than 1 y of ultrasound experience (group C). Both group B and group C had no ABVS experience. The CADe system used was the QVCAD System (QView Medical, Inc., Los Altos, CA, USA). It is designed to aid radiologists in searching for suspicious areas in ABVS images. CADe results are presented to the reader simultaneously with the ABVS images; that is, the radiologists read the ABVS images concurrently with the CADe results. The cases were randomly assigned for each reader into two equal-size groups, 1 and 2. Initially the readers read their group 1 cases with the aid of CADe and their group 2 cases without CADe. After a 1-mo washout period, they re-read their group 1

    "Be Clear on Cancer" (BCOC) was a national campaign to raise awareness of breast cancer in women over seventy years old. Cancer Research UK conducted this campaign from 03 February 2014 to 15 March 2014. This study assesses its impact on breast care services. BCOC campaign guidelines for hospital trusts were used as standard comparator for this retrospective case-control study. All new patients referred to breast clinic over four months from February 2014 were included, and compared to the same period in 2013. Information was recorded for referrals, biopsy rates and pathological diagnoses. Intra & inter-group comparisons were performed. 1646 patients were included. An increase of 25.2%(n = 184) was observed in referrals in 2014(n = 915) compared to 2013(n = 731). Cancer detection rates went down significantly (P = 0.002,Chi-square) in 2014 (5.1%,n = 47) compared to 2013 (9.0%,n = 66) due to the increase in number of referrals. In the over 70s group, a higher than predicted increase of 64.2%(n = 52) in all referrals, and 8%(n = 44) in two-week wait referrals was observed. The number of biopsies and cancers detected remained stable although the proportions undergoing biopsies (2014-29.3%,n = 39/133 versus 2013-38.3%,n = 31/81) or being diagnosed with cancer (2014-19.5%,n = 26/133 versus 2013-30.9%,n = 25/81) declined significantly (P = 0.001,McNemar) during the campaign due to an inflation in the number of referrals. Despite the overall reduction, cancer detection rate for biopsies performed remained significantly high in the over 70s (66.7%,n = 26/39) when compared with the under 70s (23.9%,n = 21/88) during the campaign. Although "Be Clear on Cancer" campaign resulted in a significant increase in breast cancer referrals, it did not translate into an increase in biopsy rates or cancer detection rates. The amount of work generated for the hospital because of this campaign was far greater than the predicted increase from campaign pilots

    Full Text Available Abstract Introduction Mycobacterium fortuitum is a rapidly growing group of nontuberculous mycobacteria more common in patients with genetic or acquired causes of immune deficiency. There have been few published reports of Mycobacterium fortuitum associated with breast infections mainly associated with breast implant and reconstructive surgery. Case presentation We report a case of a 51-year-old Caucasian woman who presented to our one-stop breast clinic with a two-week history of left breast swelling and tenderness. Following triple assessment and subsequent incision and drainage of a breast abscess, the patient was diagnosed with Mycobacterium fortuitum and treated with antibiotic therapy and surgical debridement. Conclusion This is a rare case of a spontaneous breast abscess secondary to Mycobacterium fortuitum infection. Recommended treatment is long-term antibacterial therapy and surgical debridement for extensive infection or when implants are involved.

  5. Chromosomal differences between acute nonlymphocytic leukemia in patients with prior solid tumors and prior hematologic malignancies. A study of 14 cases with prior breast cancer

    1989-01-01

    A cytogenetic study of 14 patients with secondary acute nonlymphocytic leukemia (S-ANLL) with prior treatment for breast cancer is reported. The chromosomes recurrently involved in numerical or structural anomalies are chromosomes 7, 5, 17, and 11, in decreasing order of frequency. The distribution of the anomalies detected in this sample of patients is similar to that observed in published cases with prior breast or other solid tumors, though anomalies of chromosome 11 were not pointed out, but it significantly differs from that of the S-ANLL with prior hematologic malignancies. This difference is principally due to a higher involvement of chromosome 7 in patients with prior hematologic malignancies and of chromosomes 11 and 17 in patients with prior solid tumors. A genetic determinism involving abnormal recessive alleles located on chromosomes 5, 7, 11, and 17 uncovered by deletions of the normal homologs may be a cause of S-ANLL. The difference between patients with prior hematologic malignancies or solid tumors may be explained by different constitutional mutations of recessive genes in the two groups of patients

    Full Text Available Abstract Background Breast spindle cell tumours (BSCTs, although rare, represent a heterogeneous group with different treatment modalities. This work was undertaken to evaluate the utility of fine needle aspiration cytology (FNAC, histopathology and immunohistochemistry (IHC in differentiating BSCTs. Methods FNAC of eight breast masses diagnosed cytologically as BSCTs was followed by wide excision biopsy. IHC using a panel of antibodies against vimentin, pan-cytokeratin, s100, desmin, smooth muscle actin, CD34, and CD10 was evaluated to define their nature. Results FNAC defined the tumors as benign (n = 4, suspicious (n = 2 and malignant (n = 3, based on the cytopathological criteria of malignancy. Following wide excision biopsy, the tumors were reclassified into benign (n = 5 and malignant (n = 3. In the benign group, the diagnosis was raised histologically and confirmed by IHC for 3 cases (one spindle cell lipoma, one myofibroblastoma and one leiomyoma. For the remaining two cases, the diagnosis was set up after IHC (one fibromatosis and one spindle cell variant of adenomyoepithelioma. In the malignant group, a leiomyosarcoma was diagnosed histologically, while IHC was crucial to set up the diagnosis of one case of spindle cell carcinoma and one malignant myoepithelioma. Conclusion FNAC in BSCTs is an insufficient tool and should be followed by wide excision biopsy. The latter technique differentiate benign from malignant BSCTs and is able in 50% of the cases to set up the definite diagnosis. IHC is of value to define the nature of different benign lesions and is mandatory in the malignant ones for optimal treatment. Awareness of the different types of BSCTs prevents unnecessary extensive therapeutic regimes.

    Oncoplastic breast conserving surgery (OBCS) allows women who may otherwise have mastectomy and immediate reconstruction (MxIR) the choice to conserve their breast yet avoid deformity. We compared the outcome of these options. Two cohorts meeting study criteria were identified from prospectively audited series of women undergoing OBCS or MxIR. After case matching for age, tumour size and date of surgery, stratification by breast size and controlling for radiotherapy; body image scale (BIS) scores of psychosocial function and patient reported outcome measures (PROMs) for breast appearance and return to function were analysed. A total of 567 women (286 treated by OBCS and 281 by MxIR) fulfilled inclusion criteria. Demographics were similar between the two unmatched cohorts, except for radiotherapy, age and tumour size (all p < 0.001). Overall, BIS score (p = 0.002), self-rated breast appearance, return to work and function (all p < 0.001) significantly favoured OBCS. Case-matched women with larger breasts treated by OBCS reported better BIS scores (mean 3.30 vs. 5.37, p = 0.011) and self-rated breast appearance score (p < 0.001) than MxIR, whereas no significant difference was observed for smaller breasts. BIS and appearance favoured OBCS, regardless of whether radiotherapy would have been avoided if treated by MxIR. OBCS offers suitable women the option to avoid MxIR while providing faster recovery. Better psychosocial and self-rated satisfaction with breast appearance is achieved for OBCS in all groups, regardless of the need for radiotherapy, apart from those women with smaller breasts for whom the results are comparable.

    To examine the association of plasma carotenoids, micronutrients in fruits, and vegetables, with risk of premalignant breast disease (PBD) in younger women. Blood samples were collected at the Siteman Cancer Center between 2008 and 2012 from 3537 women aged 50 or younger with no history of cancer or PBD. The analysis included 147 participants diagnosed with benign breast disease or breast carcinoma in situ during a 27-month follow-up and 293 controls. Cases and controls were matched on age, race/ethnicity, and date of and fasting status at blood draw. Plasma carotenoids were quantified. We used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs) and linear regression to assess racial differences in plasma carotenoids. The risk reduction between the highest and lowest tertiles varied by carotenoid, with β-cryptoxanthin having the greatest reduction (OR 0.62; 95% CI, 0.62-1.09; P trend  = 0.056) and total carotenoids the least (OR 0.83; 95% CI, 0.48-1.44; P trend  = 0.12). We observed an inverse association between plasma carotenoids and risk of PBD in obese women (BMI ≥ 30 kg/m 2 ; 61 cases and 115 controls) but not lean women (BMI carotenoids and risk of PBD in younger women, consistent with inverse associations reported for invasive breast cancer. Carotenoids may play a role early in breast cancer development.

    The study was conducted with an objective to investigate the association between reproductive factors, nutritional status and serum 25(OH)D levels among women diagnosed with breast cancer (BC). A total of 200 women with BC attending a tertiary healthcare institute of Delhi, India matched with 200 healthy women for age (±2years) and socio economic status were included in the study. Data was collected on socio-demographic profile, reproductive factors, physical activity and dietary intake (24h dietary recall and food frequency questionnaire) using interviewer administered structured questionnaires and standard tools. Non fasting blood samples (5ml) were collected for the biochemical estimation of serum 25(OH)D and calcium levels by chemiluminescent immunoassay and colorimetric assay technique. Data was analyzed by univariable conditional logistic regression and significant variables with (p<0.05), were analyzed in final model by conditional multivariable logistic regression analysis. The mean age of patients at diagnosis of BC was 45±10years. Results of multivariable conditional logistic regression analysis revealed significantly higher odds of BC for reproductive factors like age at marriage (more than 23 years), number of abortions, history or current use of oral contraceptive pills (OCP), with [OR (95% CI)] of [2.4 (1.2-4.9)], [4.0 (1.6-12.6)], [2.4 (1.2-5.0)]. Women with physically light activities and occasional consumption of eggs were found to have higher odds of BC [4.6 (1.6-13.0)] and [3.2 (1.6-6.3)]. Women with serum 25(OH)D levels less than 20ng/ml and calcium levels less than 10.5mg/dl had higher odds of having BC [2.4 (1.2-5.1)] and [3.7 (1.5-8.8)]. A protective effect of urban areas as place of residence and energy intake greater than 50% of Recommended Dietary Allowance (RDA) per day against BC was observed (p<0.05). The findings of the present study revealed a significant association of reproductive and dietary factors in addition to sedentary

    A case of furuncular myiasis of the breast due to infestation by the larva of Cordylobia anthropophaga in a young lady is presented. Some of the physical presentations of Cordylobia anthropophaga mastitis are similar to those of carcinoma of the breast. High index of suspicion in endemic areas, including patients who had visited such areas, the characteristic intense itching of the affected breast, the use of the magnifying hand lens and subsequent extraction of the offending maggots are the invaluable aids to diagnosis and treatment. The ulcer left on the breast after extraction of the maggot should be biopsied and the associated ill defined mass and skin changes must be seen to resolve completely before carcinoma of the breast can be safely ruled out. The various methods of extraction and the preventive measures are highlighted. Though furuncular myiasis has been reported to involve every part of domestic animals, this is the first reported case in literature involving the human breast.

    In France, the national breast cancer-screening program is based on mammography combined with clinical breast examination, and sometimes breast ultrasound for patients with high breast density. Digital breast tomosynthesis is a currently assessed 3D imaging technique in which angular projections of the stationary compressed breast are acquired automatically. When combined with mammography, clinicians can review both conventional (2D) as well as three-dimensional (3D) data. The purpose of this article is to review recent reports on this new breast imaging technique and complements this information with our personal experience. The main advantages of tomosynthesis are that it facilitates the detection and characterization of breast lesions, as well as the diagnosis of occult lesions in dense breasts. However, to do this, patients are exposed to higher levels of radiation than with 2D mammography. In France, the indications for tomosynthesis and its use in breast cancer-screening (individual and organized) are yet to be defined, as is its role in the diagnosis and staging of breast cancer (multiple lesions). Further studies assessing in particular the combined reconstruction of the 2D view using 3D tomosynthesis data acquired during a single breast compression event, and therefore reducing patient exposure to radiation, are expected to provide valuable insight.

    Full Text Available BACKGROUND Worldwide, breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting for treatment has two common problems in treatment. Achieving local control and prolonging survival by preventing or delaying distant metastasis. Today, treatment of LABC requires a combination of systemic and local/regional therapies. The aim of the study is to study the clinicopathological presentation, age distribution and various modes of management of locally advanced breast carcinoma. Worldwide breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting treatment. MATERIALS AND METHODS The present study includes 50 patients who attended Department of General Surgery for a period of three years. RESULTS The patients were regularly followed up and at the end of the study 35 (70% of the patients were doing well. 4(8% of the patients developed distant metastasis and 3 (6% of the patients developing local recurrence. 8 (16% of the patients were lost follow up. CONCLUSION About half of the cases presenting with breast cancer are in locally advanced stages. Multimodality therapy is the effective treatment of locally advanced carcinoma of breast. Breast cancer management is a challenge and improvement in therapies are needed for disease-free interval and overall survival period.

  6. Tissue microarrays for testing basal biomarkers in familial breast cancer cases

    Directory of Open Access Journals (Sweden)

    Rozany Mucha Dufloth

    Full Text Available CONTEXT AND OBJECTIVE: The proteins p63, p-cadherin and CK5 are consistently expressed by the basal and myoepithelial cells of the breast, although their expression in sporadic and familial breast cancer cases has yet to be fully defined. The aim here was to study the basal immunopro-file of a breast cancer case series using tissue microarray technology. DESIGN AND SETTING: This was a cross-sectional study at Universidade Estadual de Campinas, Brazil, and the Institute of Pathology and Mo-lecular Immunology, Porto, Portugal. METHODS: Immunohistochemistry using the antibodies p63, CK5 and p-cadherin, and also estrogen receptor (ER and Human Epidermal Receptor Growth Factor 2 (HER2, was per-formed on 168 samples from a breast cancer case series. The criteria for identifying women at high risk were based on those of the Breast Cancer Linkage Consortium. RESULTS: Familial tumors were more frequently positive for the p-cadherin (p = 0.0004, p63 (p < 0.0001 and CK5 (p < 0.0001 than was sporadic cancer. Moreover, familial tumors had coexpression of the basal biomarkers CK5+/ p63+, grouped two by two (OR = 34.34, while absence of coexpression (OR = 0.13 was associ-ated with the sporadic cancer phenotype. CONCLUSION: Familial breast cancer was found to be associated with basal biomarkers, using tissue microarray technology. Therefore, characterization of the familial breast cancer phenotype will improve the understanding of breast carcinogenesis.

    The authors report a retrospective study of 55 cases, 34 hematomas and 21 cytosteatonecrosis (CSN) of the breast, during 15 years. The mammary hematoma can appear with an encapsuled or diffused form, or in 40% of cases without radiographic model. The diagnosis of CSN, is easy, such as ringed, macrocalcified, or oil cystic, but when it is the case of solid cicatriciel mass, it is difficult to distinguish it from mammary carcinoma, in approximatively half of the cases. The etiopathogenic discussion, display, traumatic features, ischemic cellular disease, such as mammary infarct, inflammatory lesions, duct ectasia, anticoagulant drugs, needle aspiration... Even though nodular lesion may be a carcinoma, a very suggestive lesion with spicules and skin retraction may be benign. The follow up, or histological examination by biopsie or surgery, is always essential.

    1984-01-01

    A preliminar study of prognosis factors in 8 cases of breast cancer is made. Are used as parameters the dimension, the localization and the nuclear differentiation degree (gN) of the primary tumor, the vascular invasion and the axillary histologic status (pN) and the sinus histiocytosis phenomenon. Among the studied factors, have special importance the presence of vascular invasion and the negative sinus histiocytosis (minimal or absent sinus histiocytosis). Both phenomena are considered as an expression of potential systemic disease, independent of the clinical stage. Consequently the use of chemotherapy in the surgery complementation is preconized, to a best control of the disease. (author)

    Full Text Available Oral contraceptives are known to influence the risk of cancers of the female reproductive system. Evidence regarding the relationship between injectable contraceptives and these cancers is limited, especially in black South Africans, among whom injectable contraceptives are used more commonly than oral contraceptives.We analysed data from a South African hospital-based case-control study of black females aged 18-79 y, comparing self-reported contraceptive use in patients with breast (n = 1,664, cervical (n = 2,182, ovarian (n = 182, and endometrial (n = 182 cancer, with self-reported contraceptive use in 1,492 control patients diagnosed with cancers with no known relationship to hormonal contraceptive use. We adjusted for potential confounding factors, including age, calendar year of diagnosis, education, smoking, alcohol, parity/age at first birth, and number of sexual partners. Among controls, 26% had used injectable and 20% had used oral contraceptives. For current and more recent users versus never users of oral or injectable contraceptives, the odds ratios (ORs for breast cancer were significantly increased in users of oral and/or injectable contraceptives (OR 1.66, 95% CI 1.28-2.16, p<0.001 and separately among those exclusively using oral (1.57, 1.03-2.40, p = 0.04 and exclusively using injectable (OR 1.83, 1.31-2.55, p<0.001 contraceptives; corresponding ORs for cervical cancer were 1.38 (1.08-1.77, p = 0.01, 1.01 (0.66-1.56, p = 0.96, and 1.58 (1.16-2.15, p = 0.004. There was no significant increase in breast or cervical cancer risk among women ceasing hormonal contraceptive use ≥10 y previously (p = 0.3 and p = 0.9, respectively. For durations of use ≥5 y versus never use, the ORs of ovarian cancer were 0.60 (0.36-0.99, p = 0.04 for oral and/or injectable contraceptive use and 0.07 (0.01-0.49, p = 0.008 for injectable use exclusively; corresponding ORs for endometrial cancer were 0

    In 30 states, women who have had screening mammography are informed of their breast density on the basis of Breast Imaging Reporting and Data System (BI-RADS) density categories estimated subjectively by radiologists. Variation in these clinical categories across and within radiologists has led to discussion about whether automated BI-RADS density should be reported instead. To determine whether breast cancer risk and detection are similar for automated and clinical BI-RADS density measures. Case-control. San Francisco Mammography Registry and Mayo Clinic. 1609 women with screen-detected cancer, 351 women with interval invasive cancer, and 4409 matched control participants. Automated and clinical BI-RADS density assessed on digital mammography at 2 time points from September 2006 to October 2014, interval and screen-detected breast cancer risk, and mammography sensitivity. Of women whose breast density was categorized by automated BI-RADS more than 6 months to 5 years before diagnosis, those with extremely dense breasts had a 5.65-fold higher interval cancer risk (95% CI, 3.33 to 9.60) and a 1.43-fold higher screen-detected risk (CI, 1.14 to 1.79) than those with scattered fibroglandular densities. Associations of interval and screen-detected cancer with clinical BI-RADS density were similar to those with automated BI-RADS density, regardless of whether density was measured more than 6 months to less than 2 years or 2 to 5 years before diagnosis. Automated and clinical BI-RADS density measures had similar discriminatory accuracy, which was higher for interval than screen-detected cancer (c-statistics: 0.70 vs. 0.62 [P automated and clinical BI-RADS categories: fatty, 93% versus 92%; scattered fibroglandular densities, 90% versus 90%; heterogeneously dense, 82% versus 78%; and extremely dense, 63% versus 64%, respectively. Neither automated nor clinical BI-RADS density was assessed on tomosynthesis, an emerging breast screening method. Automated and clinical BI

    Sparganosis of the breast is a quite rare parasitic infection of humans and presents as soft tissue masses that mimic breast malignancy or benign tumor, such as fibroadenoma. We present here a case of histologically confirmed breast sparganosis in the upper inner quadrant of the right breast with coexisting breast cancer in the ipsilateral breast upper outer quadrant. Ultrasonography of breast sparganosis showed a well defined, tubular hypoechoic mass with discrete multilayered wall and tubule-in tubule appearance, surrounded by heterogenous hyperechoic areas in the subcutaneous fat layer of the breast. MRI revealed an elongated tubular structure with persistent and progressive enhancement. This is the second report concerned with the MRI and ultrasonographic findings of breast sparganosis and the first report of breast sparganosis in a patient with ipsilateral breast cancer

    Immunosuppression plays a pivotal role in assisting tumors to evade immune destruction and promoting tumor development. We hypothesized that genetic variation in the immunosuppression pathway genes may be implicated in breast cancer tumorigenesis. We included 42,510 female breast cancer cases and 40,577 controls of European ancestry from 37 studies in the Breast Cancer Association Consortium (2015) with available genotype data for 3595 single nucleotide polymorphisms (SNPs) in 133 candidate g...

  13. Idiopathic granulomatous mastitis: a case report of breast abscess.

    Science.gov (United States)

    Olsen, Molly L; Dilaveri, Christina A

    2011-08-04

    Idiopathic granulomatous mastitis (IGM) is an uncommon breast disease often mistaken for breast infection or abscess. We present a case of IGM diagnosed after prolonged ineffective treatment of presumed infectious mastitis with abscess. Once the diagnosis was made with biopsy and further evaluation to exclude other causes of granulomatous disease, sinus tract debridement and closure by secondary intent resulted in resolution of symptoms in our patient. Many cases of IGM require immunosuppression with steroids, methotrexate or extensive surgery. To prevent morbidity, IGM should be considered in the differential diagnosis when presumed infectious mastitis with breast abscess does not respond to usual treatment.

  14. The evolution of FDA policy on silicone breast implants: a case study of politics, bureaucracy, and business in the process of decision-making.

    Palley, H A

    1995-01-01

    The central issue facing federal regulation of breast implants is that while such devices are not functionally necessary or needed for survival, the side effects may be harmful and have not been proven unharmful. The Medical Device Amendments of 1976 appear to require such evidence prior to the FDA permitting the unrestricted marketing of these devices. However, only recently have such requirements been imposed by the FDA. The author examines the FDA's decision-making process, particularly as applied to silicone breast implants, and the factors that appears to have affected such decisions. In pursuing this study, the activities of a number of interest-group actors, as well as congressional responses and the role of federal bureaucratic actors, were examined. In 1992, the FDA established a regulatory protocol that effectively withdrew most silicone breast implants from the market for the purpose of breast augmentation and allows for the monitoring of the impact of new implants on women's health. This increase concern for determining the safety of breast implants is due to a number of factors, which are examined in this article.

Conclusão: o câncer de mama associado à gravidez mantém-se como neoplasia de mau prognóstico, não havendo diferença quando se compara com pacientes não grávidas para a mesma média de faixa etária, sendo que o fator determinante na sobrevida é o estádio clínico avançado no momento do diagnóstico.Purpose: to report 15 breast cancer cases associated with pregnancy and to compare to a control group with breast ductal infiltrating carcinoma, evaluating clinical staging, metastatic axillary lymph node involvement, histopathologic aspects related to nuclear grade, histology grade and estrogen and progesterone hormonal receptors. Method: a retrospective study of 15 cases of patients with breast cancer associated with pregnancy, attended at Mastology Department in the Woman Health Reference Center, Pérola Byington Hospital, São Paulo, was done between September 1996 and April 2001. The evaluation of clinical staging, time of diagnosis and involved axillary lymph nodes was the main study basis. Also age, parity, histologic type, applied treatment, histologic characteristics regarding nuclear grade and histologic grade and the presence of hormonal receptors in the tumors were analyzed. Results: we observed that 7 patients (46.7% presented a locally advanced breast cancer (clinical stage IIIA and IIIB and that 3 patients (20% presented a disseminated disease at the moment of diagnosis. The patients presented on average 2.4 involved axillary lymph nodes and in only one patient the lymph nodes were free of disease (6.6%. Regarding time of diagnosis, 40% of the tumors were diagnosed during the lactational period, 46.7% during the second trimester and 13.3% during the third trimester.

    Multispectral and phase-contrast diffuse optical tomography are used to track treatment progress in a patient with locally advanced invasive carcinoma of the breast cancer during neoadjuvant chemotherapy. Two types of chemotherapy treatment including four cycles of Adriamycin/Cytoxin (AC cycles) and twelve cycles of Taxol/Herceptin (TH cycles) were applied to patient. A total of eight optical exams were performed before and within the chemotherapy. Images of tissue refractive index, and absorption and scattering coefficients, as well as oxy-hemoglobin and deoxy-hemoglobin concentrations along with scattering particle volume fraction and mean diameter of cellular components were all obtained. The tumor was identified through absorption and scattering images. Tumor shrinkage was observed during the course of chemotherapy from all the optical images. Our results show that oxy-hemoglobin, deoxy-hemoglobin and total hemoglobin in tumor decreased after chemotherapy compared to that of before chemotherapy. Significant changes in tumor refractive index along with tumor cellular morphology during the entire chemotherapy are also observed.

    A crucial issue in healthcare is how multidisciplinary teams can use indicators for quality improvement. Such teams have increasingly become the core component in both care delivery and in many quality improvement methods. This study aims to investigate the relationships between (1) team factors and the way multidisciplinary teams use indicators for quality improvement, and (2) both team and process factors and the intended results. An in-depth, multiple-case study was conducted in the Netherlands in 2008 involving four breast cancer teams using six structure, process and outcome indicators. The results indicated that the process of using indicators involves several stages and activities. Two teams applied a more intensive, active and interactive approach as they passed through these stages. These teams were perceived to have achieved good results through indicator use compared to the other two teams who applied a simple control approach. All teams experienced some difficulty in integrating the new formal control structure, i.e. measuring and managing performance, in their operational task, and in using their 'new' managerial task to decide as a team what and how to improve. Our findings indicate the presence of a network of relationships between team factors, the controllability and actionability of indicators, the indicator-use process, and the intended results.

    Full Text Available Primary tuberculosis of the breast is a rare disease. It usually occurs in female of reproductive age. Any form of tuberculosis mastitis may present with feature of malignancy. Diagnosis is mainly based on identification of tubercle bacilli. We report a 42-year-old woman with primary tuberculosis abscess of the breast, who underwent surgical resection. Fine needle biopsy failed to achieve specific diagnosis before surgical operation. She responded to anti-TB therapy postoperatively. In endemic area, tuberculosis should be considered in the differential diagnosis of breast tumors

    Our aim was to identify the predictive factors of degeneration of the fibrocystic mastopathy. This work is a retrospective survey of 111 observations of isolated fibrocystic mastopathies or associated to a breast cancer among 542 women admitted for tumor of the breast during one period of 13 active years from 1991 to 2003. The diagnosis has been gotten by anatomo-pathologic exam in 95.5% (106 cas) on the operative piece and 4.5% (5 cas) on a material of biopsy. The fibrocystic mastopathy represented 30% of the set of the benign tumors of the breast. They were associated to a breast cancer in 45 cases (40.5%). The isolated benign fibrocystic mastopathy was observed in 66 cases with a middle age of 37 years, whereas the shapes associated to a breast carcinoma were noted in 45 cases. The middle age was 53 years. The non proliferative fibrocystic mastopathy is the most frequent histological type and represent 54.6% of the cases. The proliferative form with atypies was observed at 21 women (46.8%). The carcinoma the more frequently associated to the fibrocystic mastopathy was the infiltrating canalled carcinoma in 91% of cases, with a predominance of the II rank (SBR). The discovery of a mastopathy must search a luteal failure and risk factors of breast cancer notably a proliferative shape of mastopathy with atypies.

    Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy. Current information regarding this entity is scant, mainly build upon its rarity. In this paper we assess the clinical presentation, the step-by-step diagnosis, the treatment and the importance of immunohistochemistry in this uncommon condition.

    The relation between hopelessness/helplessness versus the Beck Depression Inventory (BDI) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study before. We, therefore, investigated hopelessness and helplessness versus the BDI in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus the BDI before any diagnostic procedures were carried out. In the self-rating score (SRS), the hopelessness and the helplessness versus the BDI were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness and helplessness versus the BDI in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus the BDI in the BBD and BC groups and in the ERS in helplessness versus the BDI in the HSS and BBD groups. The unweighted kappa values in the ERS for hopelessness versus the BDI in the HSS and BBD groups were statistically highly significant and the unweighted kappa values in the ERS for helplessness versus the BDI in the BBD and BC groups were statistically significant. The results of this study support a powerful link between hopelessness and helplessness versus BDI in the self-rating and examiner-rating. This finding is of clinical importance since, in the breast cancer diagnostic unit, the patients with hopelessness/helplessness characteristics and high BDI score might be associated with a difficulty and delay in reaching BC diagnosis.

    2017-04-01

    Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

    Chamorro Pacific Islanders in the Mariana Islands have breast cancer incidence rates similar to, but mortality rates higher than, those of U.S. women. As breast cancer risk factors of women of the Mariana Islands may be unique because of ethnic and cultural differences, we studied established and suspected risk factors for breast cancer in this unstudied population. From 2010-2013, we conducted retrospective case-control study of female breast cancer (104 cases and 185 controls) among women in the Mariana Islands. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for each of various lifestyle-related factors from logistic regression of breast cancer, in all women and in pre- and postmenopausal women separately. Tests for interaction of risk factors with ethnicity were based on the Wald statistics for cross-product terms. Of the medical and reproductive factors considered - age at menarche, breastfeeding, number of live births, age at first live birth, hormone use, and menopause - only age at first live birth was confirmed. Age at first live birth, among parous women, was higher among cases (mean 24.9 years) than controls (mean 23.2 years); with increased breast cancer risk (OR=2.53; 95% CI, 1.04-6.19 for age≥30y compared to risk and only in Filipino women. The association with many other established risk factors, such as BMI, hormone use and physical activity, were in the expected direction but were not significant. Associations for family history of breast cancer and alcohol intake were not evident CONCLUSIONS: The results provide a basis for cancer prevention guidance for women in the Mariana Islands.

    The relation between scoring for hopelessness/helplessness and the Montgomery-Asberg Depression Rating Scale (MADRS) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study. We, therefore, investigated hopelessness and helplessness scores versus the MADRS in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness, and for the MADRS before any diagnostic procedures were carried out. In the self-rating score (SRS), hopelessness/helplessness versus the MADRS were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness/helplessness versus the MADRS in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) for hopelessness versus the MADRS in the HSS, BBD and BC groups and for helplessness versus the MADRS in the HSS, BBD and BC groups. The unweighted kappa values in the ERS for hopelessness versus the MADRS were statistically highly significant for the HSS, BBD and BC groups and those for helplessness versus the MADRS in the HSS and BBD groups were statistically significant. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness scores and MADRS in the SRS and ERS. In the breast cancer diagnostic unit, the identification of hopeless/helpless persons is essential in suicide prevention and it is important to assess and treat hopelessness/helplessness even though an individual may report few depressive symptoms.

    Full Text Available Abstract Introduction Breast involvement by non-Hodgkin lymphoma is particularly rare in men. We describe the case of a patient with a rapidly growing, painless gynecomastia-like nodule in the left breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation A breast biopsy from a 54-year-old Caucasian man showed the morphoimmunophenotypical features of grade 3 follicular lymphoma. Moreover, fluorescence in situ hybridization analysis showed a t(14,18 translocation suggesting breast involvement by a systemic lymphoma rather than a primary breast lymphoma. The histological diagnosis was subsequently confirmed after nodule excision. Mediastinal and abdominal node involvement was then identified on computed tomography and positron emission tomography scans during staging examinations. Our patient was treated with chemotherapy. After three years our patient experienced a right retro-areolar relapse. He then received two further cycles of chemotherapy but developed a myeloid acute leukemia and, as a result of this, he subsequently died. Conclusions The rarity of breast lymphomas, especially in men, and the problems related to the therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.

    Breast neoplasm may develop in ectopically located glandular tissue. This paper presents an interesting and rare case of a 50-year-old female who despite regular mammography screening examination developed an invasive accessory breast cancer. Clinical examination revealed a 2 cm - tumour localized 4 cm below the left infra mammary fold. The lesion was immobile, the skin and the atrophic nipple were retracted, the tumour infiltrated the thoracic wall. Oligo biopsy and additional examinations showed an invasive stage IIIB ductal breast cancer (Bloom II, G-2). The receptor status was: ER(+), PGR(+), HER2(-). The increased level of cancer antigen 15.3 was found. The patient was submitted to pre-operative chemotherapy. She also underwent surgery and subsequently post-operative chemotherapy and radiotherapy. On the basis of the presented case, it could be concluded that the accessory mammary glands are out of the image of screening breast examinations. Accessory breast cancer is usually diagnosed by clinical examination and ultrasonography. Preventive resection of accessory breast in women at high risk of developing breast cancer can be considered as the treatment of choice in most patients. (authors)

    Background: To study the patterns of clinically benign breast disease in females and to co-relate them with the pathological findings. Methods: One hundred females who attended the Surgery Outpatients Department in Indira Gandhi Medical College and Research Institute, Pondicherry, with various forms of benign breast diseases during the period from October 2011 to September 2012, were studied. Early diagnoses by doing a triple assessment like a clinical examination, FNAC or a core needle biopsy and imaging methods like ultrasonography or mammography, were made within 72 hrs from the first consultation. The clinical diagnoses were compared with the cytological or histological findings wherever possible and their accuracies were evaluated. Results: Out of the 100 female patients who were studied, 87 patients who presented with breast lumps and fibroadenoma, accounted for 48% of the cases, which was the highest number of patients. Fibrocystic changes and breast abscesses came next with 18% and 12% cases respectively. We detected 3 cases of proliferative disease with atypia and one case with florid hyperplasia, which had high and low risk factors respectively, for developing invasive carcinoma. The oldest lady of the group who was clinically diagnosed to have benign disease, was detected to have invasive ductal carcinoma. They were treated in our hospital and were advised follow up. Conclusion: Benign breast diseases are common in female patients and fibroadenoma is the commonest of them all. Triple assessment provided a quick diagnosis and it alleviated unnecessary anxiety from the patients about breast cancer. The clinical diagnosis of a breast lump, as confirmed by cytology and histology, was accurate in 91.95 % of the cases. PMID:23634406

    Application of MRI for diagnosis of breast tumors was retrospectively examined in 103 consecutive cases. Contrast enhancement, mostly by dynamic study, was performed in 83 cases using Gd-DTPA and 0.5 T superconductive apparatus. Results were compared to those of mammography and sonography. On dynamic study, carcinoma showed abrupt rise of signal intensity with clear-cut peak formation in early phase, while benign fibroadenoma showed slow rise of signal intensity and prolonged enhancement without peak formation. In 12 of 33 carcinomas (33%), peripheral ring enhancement was noted reflecting vascular stroma of histologic sections. All fibroadenomas showed homogenous enhancement without peripheral ring. In MRI, sensitivity, specificity, and accuracy were 86%, 96%, 91%. In mammography 82%, 95%, 87% and in ultrasonography 91%, 95%, 93%. Although MRI should not be regarded as routine diagnostic procedure because of expense and limited availability, it may afford useful additional information when standard mammographic findings are not conclusive.

    In addition to tumor invasion and angiogenesis, matrix metalloproteinase (MMP)9 also contributes to carcinogenesis and tumor growth. Genetic variation that may influence MMP9 expression was evaluated among participants of the Shanghai Breast Cancer Genetics Study (SBCGS) for associations with breast cancer susceptibility. In stage 1, 11 MMP9 single nucleotide polymorphisms (SNPs) were genotyped by the Affymetrix Targeted Genotyping System and/or the Affymetrix Genome-Wide Human SNP Array 6.0 among 4,227 SBCGS participants. One SNP was further genotyped using the Sequenom iPLEX MassARRAY platform among an additional 6,270 SBCGS participants. Associations with breast cancer risk were evaluated by odds ratios (OR) and 95% confidence intervals (CI) from logistic regression models that included adjustment for age, education, and genotyping stage when appropriate. In Stage 1, rare allele homozygotes for a promoter SNP (rs3918241) or a non-synonymous SNP (rs2274756, R668Q) tended to occur more frequently among breast cancer cases (P value = 0.116 and 0.056, respectively). Given their high linkage disequilibrium (D' = 1.0, r (2) = 0.97), one (rs3918241) was selected for additional analysis. An association with breast cancer risk was not supported by additional Stage 2 genotyping. In combined analysis, no elevated risk of breast cancer among homozygotes was found (OR: 1.2, 95% CI: 0.8-1.8). Common genetic variation in MMP9 was not found to be significantly associated with breast cancer susceptibility among participants of the Shanghai Breast Cancer Genetics Study.

    Previous studies indicated that breast cancer is wildly spread especially in women as compared to men. It is increased after an age of thirty five years in women so it is important to study the effect of exposure to the radiation on the intact breast during the treatment of the breast suffering from cancer. In this work the scattered doses for the intact breast during the treatment of the breast suffering from cancer were measured and also the probability of inducing cancer in it is also discussed. The study was performed for a group of patients composed of twenty five females. Also the backscattered doses to the intact breast were measured for thirteen female patients. During the treatment using gamma rays from Co-60 source the two tangential fields (lateral and medial) were selected for the measurements. The results of exposure to gamma radiation for the lateral and medial fields showed that the mean scattered and backscattered doses to the intact breast were (241.26 cGY,47.49 cGY) and (371.6 cGY,385.4 cGY), respectively. Beside that the somatic risk of induced cancer to the intact breast was found to be (6 .1X10 -3 ,1.2X10 -3 ) and (9.29X10 -3 , 9.63X10 -3 ), respectively. From the results obtained it was concluded that the intact breast received small amounts of radiation doses which may lead to breast cancer for the healthy breast. The recommendations from the present study are to take care of radiation protection to the patient, and also to take care of the patient treatment conditions like temperature, pressure and humidity during the radiation exposure.(Author)

    Full Text Available Abstract Introduction The incidence of tuberculosis is rising worldwide and rare manifestations of the past are seen more often nowadays. Mammary tuberculosis is a rare clinical entity, often mimicking breast cancer or abscesses of benign or malignant origin. Clinical awareness is necessary during diagnostic work-up for establishing the correct diagnosis and treatment. Case presentation We present a case of breast tuberculosis diagnosed in a 73 year old woman at our institution. The patient presented with a palpable mass of the right breast with clinical, laboratory and mammographic findings indicative of breast carcinoma. The patient underwent lumpectomy and sentinel lymph node biopsy. Frozen section of the tumor and the sentinel node revealed "granulomatous inflammation", while gross examination confirmed the diagnosis of tuberculous mastitis. The patient received anti-tuberculosis therapy for six months with no side effects or any further complications. Conclusion Breast tuberculosis is an obscure disease often mistaken for carcinoma or pyogenic abscess of the breast, especially if well-defined clinical features are absent. A high index of suspicion is required because the disease can usually be treated conservatively with current antituberculous modalities while surgical intervention is reserved for rare cases only.

    To compare the diagnostic performance of single-view breast tomosynthesis (BT) with that of dual-view mammography (MX); to assess the benefit of adding the craniocaudal (CC) mammographic view to BT, and of adding BT to MX plus breast ultrasound, considered to be the reference work-up. One hundred and fifty-five consenting patients with unresolved mammographic and/or ultrasound findings or breast symptoms underwent conventional work-up plus mediolateral oblique-view BT of the affected breast. The final study set in 130 patients resulted in 55 malignant and 76 benign and normal cases. Seven breast radiologists rated the cases through five sequential techniques using a BIRADS-based scale: MX, MX + ultrasound, MX + ultrasound + BT, BT, BT + MX(CC). Multireader, multicase receiver operating characteristic (ROC) analysis was performed and performance of the techniques was assessed from the areas under ROC curves. The performance of BT and of BT + MX(CC) was tested versus MX; the performance of MX + ultrasound + BT tested versus MX + ultrasound. Tomosynthesis was found to be non-inferior to mammography. BT + MX(CC) did not appear to be superior to MX, and MX + ultrasound + BT not superior to MX + ultrasound. Overall, none of the five techniques tested outperformed the others. Further clinical studies are needed to clarify the role of BT as a substitute for traditional work-up in the diagnostic environment. (orig.)

    Full Text Available Carcinoma of the breast is one of the commonest cancers occurring in female and accounts for 1/3rd of all the malignant diseases occurring in them. It is mainly a disease of the developed countries and accounts for 1,00,000 deaths annually. Breast carcinoma is classified as Early breast cancer, Locally advanced breast cancer and Metastatic breast cancer. By definition early stage breast cancer constitutes breast tumors of clinical stages I, IIa and T2N1M0. Early breast cancer is the one diagnosed by mammography. Women when approaches at this stage, they can go for breast conservation surgery. Not all women are candidates for this approach, and some require mastectomy as part of their treatment. AIM To observe the incidence of early breast carcinoma with particular reference to the time taken by the patients to seek medical advice after the symptoms have developed i.e. the average time taken by the patients to seek medical advice, their appropriate management and prognosis. MATERIALS AND METHODS This prospective study was conducted over a period of 2 years from Oct-2012 to Oct-2014 in 30 female patients aged between 25-65 years who were presented with lump in breast of size ≤5cms with or without pain, with or without lymph nodes to the outpatient department. All the patients were thoroughly asked about history, examined clinically, investigated, staged and managed by surgery either Breast Conservation Surgery or Modified Radical Mastectomy. Postoperative complications were recorded and followed up regularly. RESULTS The incidence of early breast cancer in this study was 0.98% with peak age incidence between 40-60 years and duration of symptoms <6 months in 18 patients. Breast Conservation Surgery + axillary dissection + Radiotherapy was done in 23%. Prognosis was good in these patients with no local recurrence and death. CONCLUSION The prognosis of early stage breast carcinoma patients in this study was good. To have long term tumor free and

    The aim of this study is to outline a general process for assessing the feasibility of performing a valid network meta-analysis (NMA) of randomized controlled trials (RCTs) to synthesize direct and indirect evidence for alternative treatments for a specific disease population. Several steps to assess the feasibility of an NMA are proposed based on existing recommendations. Next, a case study is used to illustrate this NMA feasibility assessment process in order to compare everolimus in combination with hormonal therapy to alternative chemotherapies in terms of progression-free survival for women with advanced breast cancer. A general process for assessing the feasibility of an NMA is outlined that incorporates explicit steps to visualize the heterogeneity in terms of treatment and outcome characteristics (Part A) as well as the study and patient characteristics (Part B). Additionally, steps are performed to illustrate differences within and across different types of direct comparisons in terms of baseline risk (Part C) and observed treatment effects (Part D) since there is a risk that the treatment effect modifiers identified may not explain the observed heterogeneity or inconsistency in the results due to unexpected, unreported or unmeasured differences. Depending on the data available, alternative approaches are suggested: list assumptions, perform a meta-regression analysis, subgroup analysis, sensitivity analyses, or summarize why an NMA is not feasible. The process outlined to assess the feasibility of an NMA provides a stepwise framework that will help to ensure that the underlying assumptions are systematically explored and that the risks (and benefits) of pooling and indirectly comparing treatment effects from RCTs for a particular research question are transparent.

    A case-control study was made on female breast cancer cases and their matched controls in the Life Span Study sample. The index cases were detected during 1958-69 among the 251 breast cancer cases ascertained originally by McGregor et al. The purpose of this study was to define the epidemiologic risk factors of breast cancer among Japanese women, to test for radiation effects in the presence of other risk factors, and to search for interactions. The survey was conducted by interview at home visits for those residing in the Hiroshima and Nagasaki areas, and by mail survey for others. The interview was carried out by several trained interviewers. Information concerning suspected risk factors of breast cancer, such as familial history, education, age at menarche and menopause, marital history, reproductive history, history of breast feeding, etc., was collected for both index cases and controls. Out of 183 original pairs, analysis was made on 164 pairs with available information for both the index and control, using the method of matched samples described by Mantel and Haenszel. There was enhancement of risk for those exposed to high radiation dose (100 rad or more). Although most major results were similar to those of previous studies, a significant increase of risk was observed among those under one of the following conditions: actual duration of marriage was less than 10 years; number of pregnancies was two or less; and age at delivery of first live born child was 27 or over. These factors had a mutual interrelationship and cases with two or more of these risk factors showed higher risk than those with one. Additive interrelationship was demonstrated between radiation dose and these marital or reproductive risk factors in elevating the relative risk of breast cancer. (author)

    Full Text Available INTRODUCTION: Cancer of breast is the second most common cause of cancer in women. In the present era, late marriage, late child birth, shorter period of breast feeding and nulliparity or low parity have contributed to increase in the number of cases. Fine needle aspiration cytology (FNAC is a useful method for initial evaluation and diagnosis of breast cancers and it has the ability of providing necessary prognostic predictive information. AIMS AND OBJECTIVES: The aim of the present study is to evaluate t he accuracy of FNAC of breast lesions with histopathological correlation. To study the cytomorphological features of palpable breast lumps. To study the various cytological patterns in aspirates from breast lesions and to classify them into non - neoplastic, benign and malignant lesions. To correlate the cytology findings with subsequent histopathological diagnosis wherever possible. To establish accuracy and efficacy of aspiration cytology as an early and preoperative diagnostic aid. To compare the statistic al analysis of present study with other contemporary studies.

    Few epidemiological studies have included Hispanics with the evaluation of the effects of cigarette smoking and breast cancer. We examined the relationship between cigarette smoking, ethnicity, and breast cancer risk using data from the Breast Cancer Health Disparities Study (BCHDS). The BCHDS is a consortium of three population-based case-control studies, including U.S. non-Hispanic whites (NHWs) (1,525 cases; 1,593 controls), U.S. Hispanics/Native Americans (1,265 cases; 1,495 controls), and Mexican women (990 cases; 1,049 controls). Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Breast cancer risk was elevated among Mexican former smokers (OR 1.43, 95% CI 1.04-1.96) and among those who smoked ≥ 31 years (OR 1.95, 95% CI 1.13-3.35), compared to never smokers. In addition, Mexican former smokers with a history of alcohol consumption had increased breast cancer risk (OR 2.30, 95% CI 1.01-5.21). Among NHW premenopausal women, breast cancer risk was increased for smoking ≥ 20 cigarettes per day (OR 1.61, 95% CI 1.07-2.41). Our findings suggest the possibility of ethnic differences with the associations between cigarette smoking and breast cancer risk.

    Myiasis, parasitic infestation of the body by fly larvae, caused by the Cordylobia rodhaini is very rare with only fourteen cases published since 1970. We present a rare case of myiasis mimicking a breast abscess. A 17-year-old female presented with a nodular ulcerative lesion in her left breast 14days following a trip to Ghana. She had been initially unsuccessfully treated with the antibiotic flucloxacillin following a misdiagnosis of a breast abscess. Following application of Vaseline to the breast wound, covering the wound for 2h and gentle manipulation the larvae was removed successfully and the patient made a good recovery. Presenting as an inflammatory papule with central opening oozing serosanguinous fluid myiasis secondary to C. rodhaini can easily be mistaken for a breast abscess, often avoiding detection by unsuspecting surgeons on initial assessment. In turn ineffective antibiotic treatment is often prescribed leading to further disease progression and associated morbidity. Myiasis secondary to C. rodhaini is a rare but important differential surgeons should consider in women presenting with an inflammatory breast lesion with a recent history of foreign travel to ensure timely diagnosis and treatment. Ultrasound imaging can be useful in confirming diagnosis and avoiding treatment delays. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    The established theory that breast density is an independent predictor of breast cancer risk is based on studies targeting white women in the West. More Asian women than Western women have dense breasts, but the incidence of breast cancer is lower among Asian women. This meta-analysis investigated the association between breast density in mammography and breast cancer risk in Asian women. PubMed and Scopus were searched, and the final date of publication was set as December 31, 2015. The effect size in each article was calculated using the interval-collapse method. Summary effect sizes (sESs) and 95% confidence intervals (CIs) were calculated by conducting a meta-analysis applying a random effect model. To investigate the dose-response relationship, random effect dose-response meta-regression (RE-DRMR) was conducted. Six analytical epidemiology studies in total were selected, including one cohort study and five case-control studies. A total of 17 datasets were constructed by type of breast density index and menopausal status. In analyzing the subgroups of premenopausal vs. postmenopausal women, the percent density (PD) index was confirmed to be associated with a significantly elevated risk for breast cancer (sES, 2.21; 95% CI, 1.52 to 3.21; I 2 =50.0%). The RE-DRMR results showed that the risk of breast cancer increased 1.73 times for each 25% increase in PD in postmenopausal women (95% CI, 1.20 to 2.47). In Asian women, breast cancer risk increased with breast density measured using the PD index, regardless of menopausal status. We propose the further development of a breast cancer risk prediction model based on the application of PD in Asian women.

  11. Breast Cancer Radiotherapy Associated Diabetes Mellitus Case ...

    African Journals Online (AJOL)

    Primary breast cancer when detected early can be treated by radical mastectomy alone. However, 20-30% of women treated as such later on, develop local or regional recurrence. This leads to an additional treatment with radiotherapy by the oncologist for the sake of the 20-30% of patients that may need it postoperatively.

    Full Text Available Objective. Despite studies suggesting that triple negative breast cancer is more often seen in women of African ancestry, we report here two cases of pregnancy associated triple negative breast cancer in Hispanic women. Cases. Case one is a 37-year-old female para 2-0-0-2, who presented with a left breast mass, at 19 weeks of gestation, the biopsy of which reported an invasive ductal carcinoma, found to be triple receptor negative. The patient underwent chemotherapy during the pregnancy and was delivered with a cesarean at 37 weeks for obstetric indication. After delivery, the patient completed her chemotherapy that was followed by radical mastectomy and radiotherapy. Case two is a 28-year-old female para 6-0-1-5, who presented while breast-feeding with signs and symptoms of mastitis, and an engorged and tender right breast, five months postpartum. However, the sonogram revealed a fluid filled cavity. Aspiration and cytology did not reflect an infection and were negative for malignancy. High suspicion and lack of improvement led to biopsy that identified an invasive ductal carcinoma, found to be triple negative. The patient underwent chemotherapy followed by modified radical mastectomy. Conclusions. Triple negative breast cancer, during pregnancy or postpartum, poses a unique challenge and requires a multidisciplinary team to optimize treatment for these women.

    Evaluate concurrent Computer-Aided Detection (CAD) with Digital Breast Tomosynthesis (DBT) to determine impact on radiologist performance and reading time. The CAD system detects and extracts suspicious masses, architectural distortions and asymmetries from DBT planes that are blended into corresponding synthetic images to form CAD-enhanced synthetic images. Review of CAD-enhanced images and navigation to corresponding planes to confirm or dismiss potential lesions allows radiologists to more quickly review DBT planes. A retrospective, crossover study with and without CAD was conducted with six radiologists who read an enriched sample of 80 DBT cases including 23 malignant lesions in 21 women. Area Under the Receiver Operating Characteristic (ROC) Curve (AUC) compared the readings with and without CAD to determine the effect of CAD on overall interpretation performance. Sensitivity, specificity, recall rate and reading time were also assessed. Multi-reader, multi-case (MRMC) methods accounting for correlation and requiring correct lesion localization were used to analyze all endpoints. AUCs were based on a 0-100% probability of malignancy (POM) score. Sensitivity and specificity were based on BI-RADS scores, where 3 or higher was positive. Average AUC across readers without CAD was 0.854 (range: 0.785-0.891, 95% confidence interval (CI): 0.769,0.939) and 0.850 (range: 0.746-0.905, 95% CI: 0.751,0.949) with CAD (95% CI for difference: -0.046,0.039), demonstrating non-inferiority of AUC. Average reduction in reading time with CAD was 23.5% (95% CI: 7.0-37.0% improvement), from an average 48.2 (95% CI: 39.1,59.6) seconds without CAD to 39.1 (95% CI: 26.2,54.5) seconds with CAD. Per-patient sensitivity was the same with and without CAD (0.865; 95% CI for difference: -0.070,0.070), and there was a small 0.022 improvement (95% CI for difference: -0.046,0.089) in per-lesion sensitivity from 0.790 without CAD to 0.812 with CAD.

    Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroadenoma. Extensive cystic degeneration in a fibroadenoma, so called "cystic fibroadenoma" is very rare. Herein, we present a case of such a lesion in a 43-year-old female who has been on follow-up for fibrocystic changes of the breast, and discuss both radiological and histopathologic differential diagnosis of this lesion with other cystic lesions of the breast, including cystic papilloma. The patient is free of disease after 17 months of clinical follow-up.

    Full Text Available The incidence of tuberculosis is high in developing country; primary tuberculosis of breast is extremely rare, 3-4% of all breast lesions. Tuberculosis of breast often mimics breast cancers clinically. We are reporting here three cases of primary tuberculosis of breast presented with painless breast lump. Diagnosis was difficult and made by several parameters in different cases. Made by excision biopsy or the presence of acid-fast bacilli or Tuberculin test or Fine needle aspiration cytology of breast lump depending upon the cases. All the patients responded well to anti-tubercular regimen.

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

    Despite the fact that breast cancer is a major health issue, very few studies describe its characteristics in the Arab world or the Middle East, particularly in Lebanon. We report in this article a retrospective pilot study of the characteristics of breast cancer in Lebanon. The pathological characteristics of 624 patients diagnosed between 1990 and 2013 randomly chosen from the archives of an oncology clinic affiliated to Hotel Dieu de France Hospital are analyzed. The mean age at diagnosis is 54.6±13.4 years with 43% diagnosed before the age of 50 years. The infiltrative ductal carcinoma represents the major pathological subtype. One third of the tumors had a size of more than 2 cm at diagnosis. Estrogen-receptors are positive in more than 50% of our patients and Her2-neu is overexpresssed in 30%. Luminal A represents 45.5% and the triple negative subgroup constitutes only 8.3%. Breast cancer in Lebanon is evolving to a more indolent disease. Therefore, public awareness and institution of screening programs are required. These programs should be based on national epidemiological data and necessitate the activation of the national cancer registry. Copyright © 2015 Elsevier Ltd. All rights reserved.

    630 women patients of the Bad Trissl clinic were admitted in 1987/88 to a prospective study to find out whether scintiscanning, or radionuclide imaging, of the skeleton can be omitted completely or in part in the after care and follow-up of carcinoma of the breast. The initial criterion was a postoperative carcinoma of the breast without metastasizing in the skeleton at the time the study began or the patient was admitted to the study. Careful pain anamnesis was performed by means of prepared questions, and a detailed clinical examination conducted to detect any pain in the skeleton of the patient concerned. This was followed by whole body scintiscanning of the skeleton and complementary X-ray films, if necessary additional examinations. It was found that clinical findings and imaging methods agreed in 545 patients. In 55 cases a finding that was clinically suspicious of metastases or doubtful, could be refuted by both scintiscan and by X-ray, osseous metastasizing would have been overlooked without skeleton scintiscan in 14 patients only (2.2%), 11 of these 14 patients were high-risk patients (negative hormonal receptor status, axillary lymph node metastases). Hence, it will be sufficient to employ scintiscanning in the aftercare and follow-up of carcinoma of the breast on a risk-adapted basis provided this is preceded by careful pain analysis and clinical examination. Failure to detect metastasizing in the skeleton will then occur in only 3 of 630 patients (0.48%). In this manner 40% of scintiscans can be omitted in future. (orig.).

    1984-01-01

    A panel of Japanese and American pathologists reviewed existing histologic material used to study breast cancer risk among the A-bomb survivors in Hiroshima and Nagasaki, a population in which incidence studies have found a strong relationship between breast cancer risk and radiation dose. The primary charge to the panel was to define a body of confirmed cases in the Life Span Study sample of the Radiation Effects Research Foundation that would require little or no review for inclusion in future studies of breast cancer incidence. Broad agreement on histologic type was reached for 298 of 300 confirmed cases. The distribution of histologic types was, overall, similar to that seen in other studies of breast cancer in Japanese women, and did not appear to depend on dose; thus radiation-induced breast cancer appeared to be no different histologically from other breast cancer. Also, no evidence was found of variation in histologic type by city, age at exposure, age at diagnosis, or calendar time

    Objective: To study the clinicopathological characteristics and the prognostic determinants of the invasive lobular carcinoma breast cancer. Methods: This was a retrospective single-center study of invasive lobular breast cancer cases diagnosed from January 2008 to December 2014 at Peking University First Hospital Breast Disease Center. The study enrolled 68 invasive lobular breast cancer patients, which represented 3.64% (68/1 870) of total invasive breast cancer. The median age of all selected patients was 46 years ranging from 36 to 83 years. All patients were restaged based on the 8(th) edition of AJCC cancer staging system and follow-up data including disease-free survival (DFS) and overall survival (OS) were analyzed to explore the prognostic determinants. The 5-year OS and DFS were calculated using Kaplan-Meier method; the significance of correlations between clinicopathological features and prognostic factors was estimated using log-rank test. Results: There were significant differences in OS between patients with different anatomic stage, prognostic stage, lymph node metastasis, progesterone receptor (PR) expression, lymphvascular invasion and perineural invasion (χ(2:) 4.318 to 32.394, all P invasion (χ(2:) 4.347 to 27.369, all P invasion are the prognostic factors of invasive lobular breast cancer. Regard to invasive lobular breast cancer patients, clinicians should pay close attention to the differences between prognostic stage and anatomic stage.

    Objective: To discuss the values of three screening methods for the detection of early breast cancer, and to analyze the features of the screening cancer. Methods: The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years. The three screening methods included physical examination with ultrasound and mammography, physical examination with mammography and mammography only. The rate of recall, biopsy, cancer detection of three methods were analyzed and the mammographic findings were reviewed. Chi-square test or Fisher's exact test were used for the statistics. Results: The recall rates were 4.90% (49/1001), 6.90% (166/2407) and 4. 48% (85/1899) in three methods respectively, the biopsy rates were 1.60% (16/1001), 1.04% (25/2407) and 0.63% (12/1899), the cancer detection rates were 0.50% (5/1001), 0.17% (4/2407) and 0 (0/1899). There were statistical differences among the three groups (χ 2 =12.99,6.264,8.764, P<0.05). Physical examination with ultrasound and mammography had the highest cancer detection rate, ten breast cancers were detected and 8 were early stage breast cancer. Of seven cancers detected by mammography, only two were found by ultrasound. A cluster of calcifications were found in 2 cases, linear calcifications in 2 cases. One case presented as a asymmetric density, one as a asymmetric density with calcifications, one as multiple nodules with a cluster of calcifications. Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review. Conclusion: Physical examination with ultrasound and mammography is the best method for breast cancer screening. The breast cancer can be detected by mammography earlier than other methods.

    Digital breast tomosynthesis (DBT) is a recently developed system for three-dimensional imaging that offers the potential to reduce the false positives of mammography by preventing tissue overlap. Many qualitative evaluations of digital breast tomosynthesis were previously performed by using a phantom with an unrealistic model and with heterogeneous background and noise, which is not representative of real breasts. The purpose of the present work was to compare reconstruction algorithms for DBT by using various breast phantoms; validation was also performed by using patient images. DBT was performed by using a prototype unit that was optimized for very low exposures and rapid readout. Three algorithms were compared: a back-projection (BP) algorithm, a filtered BP (FBP) algorithm, and an iterative expectation maximization (EM) algorithm. To compare the algorithms, three types of breast phantoms (homogeneous background phantom, heterogeneous background phantom, and anthropomorphic breast phantom) were evaluated, and clinical images were also reconstructed by using the different reconstruction algorithms. The in-plane image quality was evaluated based on the line profile and the contrast-to-noise ratio (CNR), and out-of-plane artifacts were evaluated by means of the artifact spread function (ASF). Parenchymal texture features of contrast and homogeneity were computed based on reconstructed images of an anthropomorphic breast phantom. The clinical images were studied to validate the effect of reconstruction algorithms. The results showed that the CNRs of masses reconstructed by using the EM algorithm were slightly higher than those obtained by using the BP algorithm, whereas the FBP algorithm yielded much lower CNR due to its high fluctuations of background noise. The FBP algorithm provides the best conspicuity for larger calcifications by enhancing their contrast and sharpness more than the other algorithms; however, in the case of small-size and low

    Full Text Available Background. Breast cancer is the 5th leading cause of cancer death in Iranian women. This study analyzed 3010 women with breast cancer that had been referred to a cancer research center in Tehran between 1998 and 2014. Methods. In this retrospective study, we analyzed 3010 breast cancer cases with 32 clinical and paraclinical attributes. We checked the data quality rigorously and removed any invalid values or records. The method was data mining (problem definition, data preparation, data exploration, modeling, evaluation, and deployment. However, only the descriptive analyses’ results of the variables are presented in this article. To our knowledge, this is the most comprehensive study on breast cancer status in Iran. Results. A typical Iranian breast cancer patient has been a 40–50-year-old married woman with two children, who has a high school diploma and no history of abortion, smoking, or diabetes. Most patients were estrogen and progesterone receptor positive, human epidermal growth factor (HER negative, and P53 negative. Most cases were detected in stage 2 with intermediate grade. Conclusion. This study revealed original findings which can be used in national policymaking to find the best early detection method and improve the care quality and breast cancer prevention in Iran.

    Full Text Available Introduction. Primary osteosarcoma of the breast is a rare soft-tissue form of osteosarcoma without involvement of the skeletal system. Due to the rarity of the disease, its clinical features and optimal treatment remain unclear. Case Presentation. This case report deals with a 62-year-old woman with pure osteosarcoma of the breast. Conclusions. The prognosis of primary osteosarcoma of the breast is poor. Recurrence is frequent, and it is often associated with haematogenous spread of the disease to the lung. Treatment follows the model of sarcomas affecting other locations and must be planned in a multidisciplinary fashion. Adjuvant chemotherapy should be considered for patients with tumors showing aggressive features.

    This breast cancer is one of the most important death causes in women. Among the more frequently medical treatment for advanced breast cancer is the mastectomy. This situation leads to silicone implants as an esthetic option. There have been cases in patients with implants where cancer was frequently detected, in which a conventional radiotherapy is required. In this work is presented a study of the probable adverse effects caused by the application of high power X-rays (6-10 MV) to the silicone implants and to the surrounding tissues. In the research carried out at the clinic, none Bolus effect was detected in patients with implants. Our results prescribe that in the case of patients with implants and frequent breast cancer, the removal of implants is not necessary due radiotherapy works directly in the damaged tissues. (Author)

    In order to examine the rate of correct diagnosis by mammography at initial mass screening for breast cancer, we carried out a retrospective study of mammography findings in 267 cases of breast cancer detected at Asahikawa Cancer Screening Center. The screening was performed by physical examination, and in cases where disease was suspected, mammography, ultrasonography, and needle biopsy were done. Mammographically, 172 cases (64.4%) were cancer-positive, 58 cases (21.7%) were suspicious for cancer, and 37 cases (13.9%) were cancer-negative. Patients below 50 years of age and those with tumors of small diameter (<20 mm) showed a significantly lower rate of cancer positivity than patients aged 50 years or more and those with tumors 20 mm or more in diameter. Mammographic abnormalities were not specific, since these changes were also found in normal subjects and patients with benign diseases. Therefore, we concluded that mammography without physical examination at initial mass screening has a high risk of missing breast cancer. Mass screening for breast cancer should be performed by physical examination involving inspection and palpation at the first instance. If any suspicious findings are obtained, mammography, ultrasonography, and needle biopsy should be done. (author)

    Silicone breast implants from the French manufacturer Poly Implants Prosthèse (PIP) were recalled from the European market after the French regulator has revealed the implants contain non-medical-grade silicone filler. In December 2011, following a large increase in reported rupture rate and a possible cancer risk, the French Ministry of Health recommended consideration of the PIP explantation, regardless of their condition. In 2012, the Israel Ministry of Health recommended to replace the implants only upon suspected implant rupture. The aims of this study were to characterize breast-augmented Israeli patients with PIP implants, compare their outcomes with those of breast-augmented patients with different implant types, and review the current PIP literature. Breast-augmented patients who underwent an elective breast implant exchange in Israel between January 2011 and January 2017 were included in the study. Data were collected from electronic and physical medical files. There were 73 breast-augmented female patients with 146 PIP breast implants included in this study. Average implant age was 6.7 ± 2.79 years. Mean implant size was 342.8 ± 52.9 mL. Fourteen women (19 implants [16%]) had a high-grade capsular contracture (Baker grade 3-4). During exchange, 28 implants were found to be ruptured (19.2%). Less than 10 years following breast augmentation, PIP implants demonstrated higher rupture rate compared with other implants. Our data are comparable to overall available rupture rate. Among patients with definitive rupture diagnosis, an elective implant removal should be recommended. In cases of undamaged implants, plastic surgeons should also seriously consider PIP implant explantation. When the patient does not desire to remove the implant, an annual physical examination and breast ultrasound are recommended, beginning a year after augmentation.

    Full Text Available BACKGROUND Ultrasound is a radiation free, readily available imaging modality that is routinely used for evaluation of breast. The patient usually are for routine checkup to nonspecific symptoms with few showing specific signs and symptoms. In this study, an attempt has been made to understand the role of ultrasound in diagnosing benign lesions with a drawback focused on early malignant lesion. Also, the differentiation of solid and cystic lesions can reduce biopsy. MATERIALS AND METHODS This study was done retrospectively evaluating 131 consecutive patients. The ultrasound study included evaluation of mainly female patients with few male cases. RESULTS Most common lesions were benign lesions. Among these benign lesions, fibroadenomas and fibrocystic disease were the commonest. However, there were no early malignant lesion seen in this study. CONCLUSION Breast ultrasound is choice of investigation in benign breast diseases. Also, such lesions can be easily followed up at primary level. However, there is a limited role in detecting early malignant lesions, which will require additional workup at a higher level especially in high-risk groups.

    Purpose. - 1/ To evaluate the incidence of hypothyroidism following radiotherapy in the management of breast and nasopharyngeal carcinomas, 2/ to define the role of a systematic post therapeutic screening. Patients and methods. - From January 1996 through March 2001 a systematic evaluation of the clinical and the biological thyroid function was performed on a cohort of 84 patients that received supraclavicular irradiation. Selected patients had either a mammary (37 cases) or a nasopharyngeal (47 cases) carcinoma. Initial work up included thyroid inspection and palpation, and biological tests: serum FT4 and TSH levels, radio-immuno-chemistry, completed by dynamic thyroid stimulation, using TRH, in case of border line low T4 or isolated high TSH levels. Tests were repeated every three months the first year, and then every six months. Replacement therapy with L Thyroxine was administered in case of hypothyroidism. Results. - All selected patients had a normal function initially. With a mean two years follow up (1-5 years), 24 patients (29%) experienced hypothyroidism, half of whom (13 cases) being purely biological. Five patients (11%), with a nasopharyngeal carcinoma, presented also with associated pituitary failure. Clinical symptoms were minor or mild in all cases. Hypothyroidism was detected at a mean 21 months follow up. In 2 patients, hypothyroidism disappeared spontaneously within 6 months. Possible predictive factors were evaluated: age of the time of radiation, gender, percentage of irradiated thyroid, total dose, dose per fraction, tumour type and chemotherapy. Only age appeared significantly correlated with thyroid dysfunction (range: 10-30 years, P = 0.002). Conclusion. - Hypothyroidism is a frequent and certainly underestimated complication following radiotherapy of the neck. In such patients, a systematic clinical and biological evaluation every three months the first year, and then every six months until five years is recommended. (authors)

    Pleomorphic breast carcinoma is a rare variety of breast carcinoma, with a highly aggresive behaviour and poor prognosis, which usually presents after 50 years of age. Our case presented in a very similar way as phyllodes’ tumour of breast (even the FNAC report also suggested it as a case of phyllodes’ tumour). But postoperative histopathological report clearly revealed it as a case of this rare entity of pleomorphic carcinoma of breast

    Full Text Available Breast cancer is the most common cancer among women and the second leading cause of cancer deaths, after lung cancer. Cutaneous breast cancer metastases often develop as direct involvement and local spread and often manifest as solid painless nodules in the anterior chest wall. Internal malignant skin metastases rarely present like soft nodules, telangiectasia-like lesions, neoplastic alopecia, erysipeloides carcinoma, erythema annulare-like, herpetiformis or zosteriform, target-like, pyodermic and morphea-like lesions. In this article, we present a 49-year-old female patient describing a sensation of burning pain with erythematous papules and plaques in a zosteriform distribution. The diagnosis of zosteriform cutaneous metastases from a breast cancer was made. Majority of these cases may be misdiagnosed as herpes zoster infection and can be treated with antiviral drugs. Therefore, cutaneous metastases should be kept in mind in the differential diagnosis of lesions in zosteriform distribution.

    The patient was a 50-year-old woman who had undergone breast-conserving surgery for right breast cancer (C area, Bp+Ax, T2N0M0, Stage I, and scirrhous carcinoma), followed by irradiation at a total dose of 50 Gy in 1998. When 6 years 5 months had elapsed after the operation, redness and induration developed in the A area of the right breast. A biopsy via wedge resection was performed and the histopathological diagnosis was angiosarcoma. We could not rule out a possibility of positive surgical stump, and performed additional resection+skin grafting. No sarcoma remnant was demonstrated in the material resected additionally, but 2 years later, the patient experienced recurrence. Thus mastectomy+extended resection of the full thickness of the skin+skin grafting were performed. Postirradiation sarcoma involving the skin and vessels is a rare entity and occurs in 0.03-0.8% of all cases after radiation therapy. It metastasizes to the distant organs in an early stage and carries poor prognosis. No standard therapy for the disease has been established as yet. Early detection and extended resection are considered to contribute to an improvement of the prognosis. This paper deals with such a rare entity as postirradiation angiosarcoma developed in the residual breast after breast-conserving surgery. (author)

    Breast cancer is one of the most frequent causes of death in developed countries and it is the second cause of female mortality for malignant tumor in Cuba. We conducted an observational, analytic, transversal study of cases and controls for the purpose of evaluating the clinical, epidemiologic and genealogical behavior of breast cancer in Cienfuegos province, in a period of 6 years. The universe of the study was made up of 304 women distributed in 152 cases and 152 controls; they were surveyed after they gave their informed consent. Collected data were processed by means of methods of inferential statistics. It was observed that most of the cases were diagnosed in patients aged 50 to 59 years, with 24.34%, the most frequent type was infiltrating duct carcinoma, with 43.42%. We found statistical association with the personal history of benign breast pathology and the family history of cancer of any type. Presence of familial aggregation was observed for breast cancer in the first-degree relatives and the non-genetic risk factors; they did not show significant association with the occurrence of the disease in the studied population

    Full Text Available Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision. Unlike previously reported imaging findings, magnetic resonance imaging revealed an oval circumscribed mass with fringe-like internal architecture. We provide a review of the literature and discuss the imaging features of implant-associated fibromatosis of the breast.

    Full Text Available BACKGROUND Breast cancer remains a global health problem with an increasing incidence. Proliferative breast diseases are recognised as one of the risk factors in the development of carcinoma. This study was undertaken to know the frequency of proliferative lesions and other lesions in association with breast carcinomas in mastectomy specimens. MATERIALS AND METHODS 100 cases of excised carcinoma breast sent to the Department of Pathology for a three-year period at tertiary care centre was thoroughly examined and changes adjacent to the tumour was recorded and tissue was subjected for histopathological examination and results tabulated. RESULTS Infiltrating duct cell carcinoma, Not Otherwise Specified (NOS type was present in 89% of cases. Among the associated lesions, nonproliferative lesions constituted 16%, proliferative breast disease without atypia 29%, proliferative breast disease with atypia 10% and others 45%. Fibrocystic disease constituted 14% of cases, epithelial hyperplasia 15%, sclerosing adenosis 12% and atypical ductal hyperplasia in 10% of cases. Other types of associated lesions were duct carcinoma in situ in 4 cases. CONCLUSION Proliferative lesions adjacent to carcinoma breast were seen in 39% of cases. Fibrocystic disease, epithelial hyperplasia, sclerosing adenosis and atypical ductal hyperplasia being the commonest lesions adjacent to carcinoma breast in the present study.

    Background and purpose: In tangential beam treatments accurate dose calculation of the absorbed dose in the build-up region is of major importance, in particular when the target has superficial extension close to the skin. In most analytical treatment planning systems (TPSs) calculations depend on the experimental measurements introduced by the user in which accuracy might be limited by the type of detector employed to perform them. To quantify the discrepancy between analytically calculated and delivered dose in the build-up region, near the skin of a patient, independent Monte Carlo (MC) simulations using the PENELOPE code were performed. Dose distributions obtained with MC simulations were compared with those given by the Pencil Beam Convolution (PBC) algorithm and the Analytical Anisotropic Algorithm (AAA) implemented in the commercial TPS Eclipse. Material and methods: A cylindrical phantom was used to approximate the breast contour of a patient for MC simulations and the TPS. Calculations of the absorbed doses were performed for 6 and 18 MV beams for four different angles of incidence: 15 deg., 30 deg., 45 deg. and 75 deg. and different field sizes: 3 x 3 cm 2 , 10 x 10 cm 2 and 40 x 40 cm 2 . Absorbed doses along the phantom central axis were obtained with both the PBC algorithm and the AAA and compared to those estimated by the MC simulations. Additionally, a breast patient case was calculated with two opposed 6 MV photon beams using all the aforementioned analytical and stochastic algorithms. Results: For the 6 MV photon beam in the phantom case, both the PBC algorithm and the AAA tend to underestimate the absorbed dose in the build-up region in comparison to MC results. These differences are clinically irrelevant and are included in a 1 mm range. This tendency is also confirmed in the breast patient case. For the 18 MV beam the PBC algorithm underestimates the absorbed dose with respect to the AAA. In comparison to MC simulations the PBC algorithm tends

    Background: Male breast cancer incidence rises with age with peak in the sixth and seventh decade. It is one of the rare diseases and accounts for less than 1% of all malignancies worldwide. It is usually diagnosed in the late stage with poor prognosis. Objective: The purpose of this study was to know the demographic pattern and tumour characteristic of breast cancer in men reported at Institute of Radiotherapy and Nuclear Medicine (IRNUM), Peshawar. Methods: Retrospective data was collected from the (IRNUM), Peshawar for a period of three years (2006-2008). The evaluation was done from the histopathological reports of mastectomy and biopsy specimens. All male patients in the age group 26 -86 year with breast cancer were included in the study. The age of the patients and tumour characteristics recorded were size, grade, type, skin involvement and stage. Results: Total number of male patients with breast cancer were 31 (2.1%) out of the total patients with breast malignancy during the study period with the mean age of 58.3 years. Tumour size ranged from 2 to 12 Cm. with average of 3.6 Cm. Invasive ductal carcinoma was found in 87% , papillary carcinoma in 6.5%, each of malignant fibrous histocytoma and sarcoma in 3.2% cases. Maximum number of patients was of grade II (41%). Patients in whom stage of the disease was know n were 22 cases with 45.5% had stage III disease and 32% had stage IV disease. Skin involvement was found positive in 8 (25.8%). Conclusion: Due to poor health care system breast cancer is diagnosed in a late stage of the disease and prognosis is poor. (author)

    100 cases of breast carcinoma were studied with lectin affinitive histochemistry technology. The result showed that Ricinus comunis agglutinin (RCA1) was located in almost all intraductal carcinomas but one, while the positive rates in the other types were obviously low (P less than 0.05). The positive rate of Ulex europaeus agglutinin-I (UEA1) in well-differentiated types was higher than that in poorly-differentiated ones (P less than 0.05). The location of Peanut agglutinin (PNA), Bandeiraea Simplicifolia (BSL) and UEA1 in breast carcinomas exhibited some regularity and it might be useful in understanding the differentiation of breast carcinomas. No relationship between changes of the eight lectins and metastases in axillary lymph nodes was observed, but the authors considered that PNA-affinitive histochemistry was beneficial to the detection of micrometastases in lymph nodes.

    2003-12-01

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is a rare variety of non-Hodgkin's lymphoma which originates from CD5+ B-cell population in the mantle zones of lymphoid follicles. Coexistence of such tumours in the axillary lymph nodes with invasive breast cancers without prior history of adjuvant chemotherapy or radiotherapy has not been previously reported in literature. Case report We report a rare case of breast cancer co-existing with stage I mantle cell lymphoma of the ipsilateral axillary lymph node detected fortuitously by population screening. Conclusion Though some studies have tried to prove breast carcinomas and lymphomas to share a common molecular or viral link, more research needs to be done to establish whether such a link truly exists.

    Intracranial metastasis from breast cancer is a relatively common finding, however, the appearance of breast cancer metastasis in a meningioma is very rare. Several cases of tumor-to-tumor metastasis and collision tumors have been reported previously, with meningioma being implicated as the most common benign intracranial neoplasm to harbour the metastasis. Occasionally, the discovery of a tumor-to-meningioma metastasis may herald the diagnosis of an occult primary malignancy. Careful histopathological assessment of the resected meningioma specimen is pivotal to the management of these patients, as this will alter the treatment plan and prognosis considerably. Intracranial meningioma with collision breast cancer as primary presentation of an undiagnosed metastatic breast cancer is extremely rare. The current study presents a case of intracranial meningioma with collision breast cancer as a primary presentation, and reviews the available evidence for this unusual disease entity.

    Triple-negative breast cancer (TNBC) is associated with an aggressive clinical course due to the lack of therapeutic targets. Therefore, identifying reliable prognostic biomarkers and novel therapeutic targets for patients with TNBC is required. Proline, glutamic acid, leucine rich protein 1 (PELP1) is a novel steroidal receptor co-regulator, functioning as an oncogene and its expression is maintained in estrogen receptor (ER) negative breast cancers. PELP1 has been proposed as a prognostic biomarker in hormone-related cancers, including luminal-type breast cancers, but its significance in TNBC has not been studied. PELP1 immunoreactivity was evaluated using immunohistochemistry in 129 patients with TNBC. Results were correlated with clinicopathological variables including patient’s age, tumor size, lymph node stage, tumor grade, clinical stage, histological type, Ki-67 LI, as well as clinical outcome of the patients, including disease-free survival (DFS) and overall survival (OS). PELP1 was localized predominantly in the nuclei of carcinoma cells in TNBC. With the exception of a positive correlation between PELP1 protein expression and lymph node stage (p = 0.027), no significant associations between PELP1 protein expression and other clinicopathological variables, including DFS and OS, were found. However, when PELP1 and Ki-67 LI were grouped together, we found that patients in the PELP1/Ki-67 double high group (n = 48) demonstrated significantly reduced DFS (p = 0.005, log rank test) and OS (p = 0.002, log rank test) than others (n = 81). Multivariable analysis supported PELP1/Ki-67 double high expression as an independent prognostic factor in patients with TNBC, with an adjusted hazard ratio of 2.020 for recurrence (95 % CL, 1.022–3.990; p = 0.043) and of 2.380 for death (95 % CL, 1.138–4.978; p = 0.021). We found that evaluating both PELP1 and Ki-67 expression in TNBC could enhance the prognostic sensitivity of the two biomarkers. Therefore, we propose

    Differential diagnosis and detection of malignant lesions in mammography poses a challenge for many diagnosticians. Although mammography continues to be the best and cost-effective way to detect breast cancer, it has its limitations due in part to the radiological appearance of changes of a very rare condition. We are presented with changes that have met well-known radiologic criteria for the diagnosis of malignancy, yet they turn out to be benign, because they belong to a group of extraordinary lesions. In June 2010, a 56-year-old woman found a lump in her right breast. Mammography performed at another medical center, revealed a change 12 mm in diameter, rated as BI-RADS 4C. Physical examination revealed a palpable lesion, 15 mm in diameter. Ultrasonography revealed hypoechogenic change with ill-defined outlines, size 14×10 mm – BI-RADS 5. Fine needle aspiration biopsy was done and revealed no atypical cells. The patient underwent an open surgical biopsy and a histopathological diagnosis was suggested to be a type of Wegener’s granulomatosis. Exclusion of cancer enabled the continuation of medical treatment of the underlying disease. There were no changes in the breast in follow-up studies. The differential diagnosis of breast tumors should include rare conditions that can sometimes mimic breast cancer. One of them is Wegener’s granulomatosis. Both, the diagnosis and treatment of the disease, require the cooperation of specialists from various fields, including clinicians, pathologists and radiologists

    Sarcomas of the breast constitutes breast tumors. Liposarcoma of the breast represents 3-24% of the primary breast sarcomas. Liposarcoma can arise from pre-existing benign lesions like fibroadenoma or from lipoid tissue in the breast. There are only few cases of liposarcoma of the breast in young females reported in the literature. Liposarcoma of the breast typically involves women with age after 50 years. In this article, we present a young woman with liposarcoma of the breast. © 2010 Wiley Periodicals, Inc.

    1983-01-01

    During the past 10 years, the Southeastern Cancer Study Group (SECSG) has been engaged in one major adjuvant study and three major advanced disease studies for patients with adenocarcinoma of the breast. The adjuvant study is demonstrating that six months of adjuvant CMF is the therapeutic equivalent of 12 months and that post-operative irradiation is of no added therapeutic benefit. In patients with advanced disease, a low dose 5 drug combination of CMFVP induces more objective responses than single agent 5FU, but improves survival only for those patients with liver metastases when compared to the sequential use of the same 5 single agents. The three drug combination, CAF, utilizing doxorubicin, induces more objective responses than low dose CMFVP, but it does not improve overall survival. The addition of a phase active combination, CAMELEON, (i.e., sequentially alternating therapy) of CAF has not improved the duration of disease control and survival for patients with liver metastases, lymphangitic and nodular lung metastases compared to CAF. Aggressive combination chemotherapeutic approaches to patients with advanced disease provide better and longer disease and tumor control but only marginal improvements in overall survival. Adding additional agents to a maximally tolerable regimen has not improved the therapeutic outcome

    Background and objectives Metastasis to the breast from extra mammary sites is uncommon with an incidence ranging from 1.2 to 2 % in clinical reports. Approximately 300 cases of breast metastasis from extra mammary sites have been reported, mostly in small series or as a single case report. Gastrointestinal adenocarcinoma metastasising to the breast is also very rare and only 30 cases have been reported in the literature. Metastatic deposits within the breast may be difficult to distinguish from primary breast carcinoma. Radiological features and immunohistochemistry especially for steroid hormone receptors (ER/PR) and expression of gross cystic disease fluid protein (GCDFP) and presence of other immunohistochemistry protein factors in breast metastasis which are specific to primary site may be helpful in differentiating these two conditions. Materials and methods In this series of 3 cases of breast as an unusual site of metastasis, we present different cases of adenocarcinoma of stomach, sigmoid colon and kidney with metastasis to the breast and discuss the differential diagnosis and management plans. Conclusion In conclusion, secondary tumors to the breast are rare and thus differentiating primary tumors from metastatic breast carcinoma is important for rational and optimum therapy and avoidance of unnecessary radical surgery. Palpable breast lump without typical radiological signs of primary breast carcinoma in patients with known primary should be suspected of representing metastasis.

    The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis. Primary tumors may arise from any ectopic breast tissue. Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare. Two such cases were reported in this article. One was a 43-year-old Chinese female who exhibited bilateral breast cancer (invasive ductal carcinoma, not otherwise specified, IDC-NOS) and an accessory breast carcinoma (IDC-NOS) incidentally identified in her left axilla. The ectopic breast tissue in her right axilla presented with adenosis. The patient was surgically treated, followed by postoperative docetaxel epirubicin (TE) chemotherapy. The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified. The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen

    To compare the clinical performance of digital breast tomosynthesis (DBT) with that of full-field digital mammography (FFDM) in a diagnostic population. The study enrolled 200 consenting women who had at least one breast lesion discovered by mammography and/or ultrasound classified as doubtful or suspicious or probably malignant. They underwent tomosynthesis in one view [mediolateral oblique (MLO)] of both breasts at a dose comparable to that of standard screen-film mammography in two views [craniocaudal (CC) and MLO]. Images were rated by six breast radiologists using the BIRADS score. Ratings were compared with the truth established according to the standard of care and a multiple-reader multiple-case (MRMC) receiver-operating characteristic (ROC) analysis was performed. Clinical performance of DBT compared with that of FFDM was evaluated in terms of the difference between areas under ROC curves (AUCs) for BIRADS scores. Overall clinical performance with DBT and FFDM for malignant versus all other cases was not significantly different (AUCs 0.851 vs 0.836, p = 0.645). The lower limit of the 95% CI or the difference between DBT and FFDM AUCs was -4.9%. Clinical performance of tomosynthesis in one view at the same total dose as standard screen-film mammography is not inferior to digital mammography in two views. (orig.)

    Full Text Available Background. Breast sarcomas are a heterogeneous group of breast neoplasms with a low incidence and a reserved prognosis. No treatment protocol has been yet established, a guideline similar to soft tissue sarcomas is used. Materials and Methods. Our study analyzed all the patients admitted with the diagnosis of malignant breast disease in two specialized centers on a five-year time frame. We compared long term results for the patients who underwent conservative treatment and mastectomy. Results. A total of 76 cases received surgical treatment with curative intent, 24 conservative procedures and 52 mastectomies. Incidence of local recurrence does not appear to be closely related to the type of surgical procedure. There were a number of five local recurrences for patients who received conservative treatment and 7 local recurrences where we used mastectomy. Kaplan-Meier analysis conducted shows no differences statistically significant (sig = 0.459 between the results of conservative treatment and mastectomy. Basically conservative surgery seems to get similar results, provided that R0 resection objective can be met. Conclusions. Treatment options are more limited for breast sarcomas than carcinomas, the role of surgery being more important to therapeutic success. The biological characteristic of the tumor including histological type and sub-type, play an important role in determining the results and the treatment should be tailored and adapted for each case.

    It has been estimated that approximately 25% of all breast cancers in women can be explained by currently recognized somatic (i.e., hereditary and physiologic) risk factors. It has also been hypothesized that psychological factors may play a role in the development of breast cancer. We investigated the extent to which personality factors, in addition to somatic risk factors, may be associated with the development of primary breast cancer. We employed a prospective, longitudinal study design. From 1989 through 1990, a personality questionnaire was sent to all female residents of the Dutch city of Nijmegen who were 43 years of age or older. This questionnaire was sent as part of an invitation to participate in a population-based breast cancer screening program. Women who developed breast cancer among those who returned completed questionnaires were compared with women without such a diagnosis in regard to somatic risk factors and personality traits, including anxiety, anger, depression, rationality, anti-emotionality (i.e., an absence of emotional behavior or a lack of trust in one's own feelings), understanding, optimism, social support, and the expression and control of emotions. Conditional logistic regression analysis was used to identify variables that could best explain group membership (i.e., belonging to the case [breast cancer] or the control [without disease] group). Personality questionnaires were sent to 28 940 women, and 9705 (34%) were returned in such a way that they could be used for statistical analyses. Among the 9705 women who returned useable questionnaires, 131 were diagnosed with breast cancer during the period from 1989 through 1994. Seven hundred seventy-one age-matched control subjects (up to six per case patient) were selected for the analyses. Three variables were found to be statistically significantly associated with an increased risk of breast cancer: 1) having a first-degree family member with breast cancer (versus not having an

    Women with atypical hyperplasia (AH) on a benign breast biopsy specimen are at increased risk for the development of breast cancer. However, the relation between the type and extent of AH (atypical ductal hyperplasia [ADH] vs atypical lobular hyperplasia [ALH]) and the magnitude of the breast cancer risk is not well defined. A nested case-control study of benign breast disease and breast cancer risk was conducted. Women with breast cancer and prior benign breast biopsy findings (488 cases) were matched to women with prior benign breast biopsy findings who were free from breast cancer (1907 controls). Benign breast biopsy slides were reviewed and categorized as nonproliferative, proliferative without atypia, or AH (ADH or ALH). The number of foci of AH was also recorded. Among women with ADH, the interrelation between the extent of atypia and breast cancer risk was not significant (odds ratio [OR] for 1 or 2 foci, 3.5; 95% confidence interval [CI], 2.2-5.6; OR for ≥3 foci, 2.7; 95% CI, 1.4-5.1; P = .41). Similarly, although the risk with ALH was higher for those with ≥3 foci than for those with breast cancer risk. The lack of a significant dose-response relation between the extent and type of atypia and breast cancer risk suggests that it would be premature to use the extent of atypia to influence management decisions for women with ADH or ALH. © 2015 American Cancer Society.

    Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

    Full Text Available Abstract Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the axillary accessory breast have very seldom been reported in the English literature. We report a case of nipple adenoma arising from axillary accessory breast including clinical and pathological findings. An 82-year-old woman presented with the complaint of a small painful mass in the right axilla. Physical examination confirmed a well-defined eczematous crusted mass that was 8 mm in size. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Microscopic structural features included a compact proliferation of small tubules lined by epithelial and myoepithelial cells, and the merging of glandular epithelial cells of the adenoma into squamous epithelial cells in the superficial epidermal layer. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for axillary tumor neoplasms.

    Full Text Available The term adenomyoepithelioma has been applied to a broad range of biphasic lesions composed of epithelial and myoepithelial cells. They show diverse morphologic patterns due to the admixture of the two components which may lead to a diagnosis of malignancy. We present a case of bilateral adenomyoepithelioma in a lactating woman who had a concomitant breast abscess. A 25-year-old lady presented with bilateral breast lumps since 2 years, with acute pain. With a clinical diagnosis of an abscess, superimposed on fibrocystic disease, drainage of abscess, and lumpectomy was performed. The clinicopathological features of this entity are discussed.

    2016-01-01

    Full Text Available Introduction Breast magnetic resonance imaging (MRI is considered a more sensitive diagnostic test for detecting invasive breast cancer than mammography or breast ultrasound. Breast MRI may be particularly useful in younger premenopausal women with higher density breast tissue for differentiating between dense fibroglandular breast tissue and breast malignancies. The main objective of this study was to determine the impact of preoperative breast MRI on surgical decision-making in young women with breast cancer. Methods A retrospective review of patients with newly diagnosed invasive breast cancer and age of ≤50 years was performed. All patients underwent physical examination, preoperative mammogram, breast ultrasound, and bilateral breast MRI. Two breast cancer surgeons reviewed the preoperative mammogram report, breast ultrasound report, and physical examination summary and were asked if they would recommend a lumpectomy, a quandrantectomy, or a mastectomy. A few weeks later, the two surgeons were shown the same information with the breast MRI report and were asked what type of surgery they would now recommend. In each case, MRI was classified by two adjudicators as having affected the surgical outcome in a positive, negative, or neutral fashion. A positive impact was defined as the situation where breast MRI detected additional disease that was not found on physical examination, mammogram, or breast ultrasound and led to an appropriate change in surgical management. A negative impact was defined as the situation where breast MRI led the surgeon to recommend more extensive surgery, with less extensive disease actually found at pathology. No impact was defined as the situation where MRI findings did not alter surgical recommendations or outcomes. Results Of 37 patients whose charts were reviewed, five patients were deemed to be ineligible due to having received neoadjuvant chemotherapy, having previous breast implants, or having had their

    Full Text Available Pure mucinous carcinoma is a rare special type of breast carcinoma with a 2% incidence and it is usualy asociated with a good prognosis. It must distingished from the mixed subtype of mucinos breast carcinoma, which has an invasive non-mucinous component in more than 10% of the tumor and change the favourable outcome of the first subtype. In this report we present a case of a premenopausal woman with a lump in right breast wich histopathologically proved to be a pure mucinous carcinoma associated with high grade ductal carcinoma in situ. Immunohistochemical and ancillary studies demonstrate a great heterogeneity of the neoplastic cells, with different molecular profile for each component of the tumor. The presence of ductal carcinoma in situ with a different imunophenotype from pure mucinous carcinoma rise the ipothesis of a different tumor cell biology which may change clincal evolution.

    Full Text Available Abstract Background Primary non-Hodgkin lymphoma (NHL of the breast represents 0.04–0.5% of malignant lesions of the breast and accounts for 1.7–2.2% of extra-nodal NHL. Most primary cases are of B-cell phenotype and only rare cases are of T-cell phenotype. Anaplastic large cell lymphoma (ALCL is a rare T-cell lymphoma typically seen in children and young adults with the breast being one of the least common locations. There are a total of eleven cases of primary ALCL of the breast described in the literature. Eight of these cases occurred in proximity to breast implants, four in relation to silicone breast implant and three in relation to saline filled breast implant with three out of the eight implant related cases having previous history of breast cancer treated surgically. Adjuvant postoperative chemotherapy is given in only one case. Secondary hematological malignancies after breast cancer chemotherapy have been reported in literature. However in contrast to acute myeloid leukemia (AML, the association between lymphoma and administration of chemotherapy has never been clearly demonstrated. Case Presentation In this report we present a case of primary ALCL of the breast arising in reconstruction mamoplasty capsule of saline filled breast implant after radical mastectomy for infiltrating ductal carcinoma followed by postoperative chemotherapy twelve years ago. Conclusion Primary ALK negative ALCL arising at the site of saline filled breast implant is rare. It is still unclear whether chemotherapy and breast implantation increases risk of secondary hematological malignancies significantly. However, it is important to be aware of these complications and need for careful pathologic examination of tissue removed for implant related complications to make the correct diagnosis for further patient management and treatment. It is important to be aware of this entity at this site as it can be easily misdiagnosed on histologic grounds and to exclude

    Several studies have suggested that post-traumatic stress disorder (PTSD) is related to adverse health outcomes. There are limited data on PTSD and cancer, which has a long latency period. We investigated the association between World War II (WWII)-related PTSD and subsequent breast cancer (BC) risk among Jewish WWII survivors and examined whether this association was modified by exposure to hunger during WWII. We compared 65 BC patients diagnosed in 2005 through 2010 to 200 population-based controls who were members of various organizations for Jewish WWII survivors in Israel. All participants were born in Europe, lived at least six months under Nazi rule during WWII, and immigrated to Israel after the war. We estimated PTSD using the PTSD Inventory and applied logistic regression models to estimate the association between WWII-related PTSD and BC, adjusting for potential confounders. We observed a linear association between WWII-related PTSD and BC risk. This association remained significant following adjustment for potential confounders, including obesity, alcohol consumption, smoking, age during WWII, hunger exposure during WWII, and total number of traumatic life events (OR = 2.89, 95% CI = 1.14-7.31). However, the level of hunger exposure during WWII modified this effect significantly. These findings suggest an independent association between WWII-related PTSD and subsequent BC risk in Jewish WWII survivors that is modified by hunger, a novel finding. Future research is needed to further explore these findings.

    Full Text Available Background: The Baby-Friendly Hospital Initiative was launched in 1989 by World Health Organization and the United Nations Children's Fund for the promotion of breastfeeding. This program was implemented in many departments of gynecology and obstetrics and resulted in reduced malnutrition, infection, morbidity and mortality in children. This program has introduced 10 specific steps to support successful breastfeeding. For instance, in the fourth step, skin-to-skin contact and breastfeeding are promoted since the time of birth, and in the fifth step, mothers are instructed on how to breastfeed or persist in breastfeeding. In these ten steps, mothers are trained in various fields. Methods: In this cross-sectional study, a standardized questionnaire was used to collect data at baby-friendly hospitals. To assess the difference between multiple nominal variables, variance analysis was performed, using SPSS version 17. Results: Based on the analysis, mothers' awareness of the benefits of breast milk and breastfeeding was 83% in a baby-friendly hospital. Also, their awareness of proper breastfeeding was estimated at 78.5%. In addition, mothers' knowledge about the frequency of breastfeeding was 70%. Conclusion: Given the role of Baby-Friendly Hospital Initiative in training mothers on the importance of breastfeeding and its persistence in future, careful monitoring of these hospitals, breastfeeding support services and breastfeeding training by midwives at healthcare centers are of great importance.

    Breast cancer is the most common carcinoma in women. Comprehensive therapy on breast cancer including surgical operation, chemotherapy, radiotherapy, endocrinotherapy, etc. could help, but still has serious side effect and resistance against anticancer drugs. Complementary and alternative medicine (CAM) may avoid these problems, in which traditional Chinese medicine (TCM) has been highlighted. In this section, to analyze the mechanism through which TCM act on breast cancer, we have built a virtual model consisting of the construction of database, oral bioavailability prediction, drug-likeness evaluation, target prediction, network construction. The 20 commonly employed herbs for the treatment of breast cancer were used as a database to carry out research. As a result, 150 ingredient compounds were screened out as active molecules for the herbs, with 33 target proteins predicted. Our analysis indicates that these herbs 1) takes a 'Jun-Chen-Zuo-Shi" as rule of prescription, 2) which function mainly through perturbing three pathways involving the epidermal growth factor receptor, estrogen receptor, and inflammatory pathways, to 3) display the breast cancer-related anti-estrogen, anti-inflammatory, regulation of cell metabolism and proliferation activities. To sum it up, by providing a novel in silico strategy for investigation of the botanical drugs, this work may be of some help for understanding the action mechanisms of herbal medicines and for discovery of new drugs from plants.

  6. Sequencing analysis of SLX4/FANCP gene in Italian familial breast cancer cases.

    Directory of Open Access Journals (Sweden)

    Irene Catucci

    Full Text Available Breast cancer can be caused by germline mutations in several genes that are responsible for different hereditary cancer syndromes. Some of the genes causing the Fanconi anemia (FA syndrome, such as BRCA2, BRIP1, PALB2, and RAD51C, are associated with high or moderate risk of developing breast cancer. Very recently, SLX4 has been established as a new FA gene raising the question of its implication in breast cancer risk. This study aimed at answering this question sequencing the entire coding region of SLX4 in 526 familial breast cancer cases from Italy. We found 81 different germline variants and none of these were clearly pathogenic. The statistical power of our sample size allows concluding that in Italy the frequency of carriers of truncating mutations of SLX4 may not exceed 0.6%. Our results indicate that testing for SLX4 germline mutations is unlikely to be relevant for the identification of individuals at risk of breast cancer, at least in the Italian population.

    We conducted a retrospective study to assess the follow-up of patients with localized breast cancer and the first indicators of advanced breast cancer recurrence. All patients with advanced breast cancer recurrence treated between January 2010 and June 2016 in our institution were registered. Among these patients, 303 patients initially treated for early breast cancer with curative intent were identified. After initial curative treatment, follow-up involved the oncologist, the general practitioner and the gynecologist in 68.0%, 48.9% and 19.1% of cases, respectively. The median DFI was 4 years for luminal A, 3.8 years for luminal B, 3.7 years for HER2-positive and 1.5 years for TNBC (p = 0.07). Breast cancer tumor marker was prescribed for 164 patients (54.1%). No difference in terms of follow-up was observed according to the molecular subtype. Symptoms were the primary indicator of relapse for 143 patients (47.2%). Breast cancer recurrence was discovered by CA 15.3 elevation in 57 patients (18.8%) and by CAE elevation in 3 patients (1%). The rate of relapse diagnosed by elevation of CA 15.3 or CAE was not statistically associated with the molecular subtype (p = 0.65). Luminal A cases showed a significantly higher rate of bone metastases (p = 0.0003). TNBC cases showed a significantly higher rate of local recurrence (p = 0.002) and a borderline statistical significant higher rate of lung/pleural metastases (p = 0.07). Follow-up recommendations could be adapted in clinical practice according to the molecular subtype. General practitioners should be more involved by the specialists in breast cancer follow-up.

    Mammography is the oldest and most popular method in the diagnosis of breast disease and received the special attention as the powerful instrument in early detection of breast cancer. In Korea, the mammography has not been widely used, yet, but nowadays, increasing incidence of breast cancer and good prognosis after early detection and proper treatment need the clinical application of mammography for management of patient with breast disease and for the detection of occult cancer. The technique obtaining the good quality film is essential for improving the diagnostic accuracy of mammography in breast disease and in general, excellent film radiographs of breast can be obtained with proper combination of Kvp, processing, selection of fine grained film, fine focus tube and compression. In present study, radiographic technique was used in which 36-40 Kvp and 200 mAs were derived from a small focus Tungsten Anode tube. Medio-lateral and Cranio-caudad view were taken using Acryl compression device, which was specially designed by authors in order to properly examine the small, dense breasts of Korean women. Non-screen fine grained mammographic films was used and processing was manual.The materials consisted of 150 cases of mammography performed at Yonsei University Medical College, Severance Hospital, since January, 1978. We analyzed the diagnostic accuracy of mammography and mammographic findings in pathologically confirmed 39 cases. The conclusions are as follows: 1. Because women are sensitive to her breast changes, mammography is very useful not only in diagnosis of breast disease and early detection of cancer, but also management of patients with breast symptom and sign. 2. We obtained the relatively good quality film and high diagnostic accuracy with our own method, using conventional Tungsten Anode tube, compression device and hand processing. 3. We also applied specimen radiography in diagnosis of breast disease, which was helpful in verification of the adequacy

    Pilonidal sinus is a common entity, most often occurring in the natal cleft. Pilonidal sinus with abscess formation has also been described in hairdressers in the interdigital space. We report a case of pilonidal abscess of the breast in a hairdresser, a rarely reported site, which requires awareness on the clinician's part of this occupational risk, for appropriate management and post-surgery advice on prevention. It is particularly important to impart such information to the reporting pathologist who is key to making this histological diagnosis. PMID:24950682

    Fibromatosis is a rare benign tumor that presents predominantly as a unilateral, painless, palpable, and firm to hard mass which may be accompanied by skin dimpling and nipple retraction. It is characterized as an infiltrating fibroblastic and myofibroblastic proliferation that can behave in a locally aggressive fashion if incompletely excised. However, it is not known to metastasize. We report a case of a 39-year-old female with recurrent fibromatosis in the breast. Initially, the mass was detected by a screening mammography. It appeared as an oval mass and recurred twice after surgical excision over a 36-month period with a more suspicious appearance.

  13. Breast cancer incidence and mortality in the Canadian fluoroscopy study

    This report describes the formation of the National Cancer Incidence Reporting System in a data base format suitable for computerized record linkage, and the linkage of the data from the Canadian study of cancer following multiple fluoroscopies to that database and to the Canadian National Mortality Data Base between 1940 and 1987. A comprehensive statistical analysis of the breast cancer mortality data occurring among female members of the cohort between 1950 and 1987 with respect to exposure to low-LET radiation is reported, together with a parallel analysis of the breast cancer incidence data between 1975 and 1983. The Canadian fluoroscopy study is a cohort study of tuberculosis patients first treated in Canadian institutions between 1930 and 1952. The present mortality analysis relates to the breast cancer mortality experience between 1950 and 1987. A total of 677 deaths from breast cancer was observed in this period. The most appropriate dose-response relationship appears to be a simple linear one. There is a strong modifying influence of age at first exposure; women first exposed past the age of 30 have little excess risk due to radiation exposure. The breast cancer incidence analysis is based upon 628 cases observed between 1975 and 1983. Again a simple linear model appears to provide an adequate fit to the data. There is a suggestion of time dependency under the additive model, but this is not statistically significant. The results from this latest analysis continue to be reassuring in terms of radiation risk from mammography. (L.L.) 15 refs., figs., tabs

  14. A population-based study of the effectiveness of breast conservation for newly diagnosed breast cancer

    Purpose: Our objective was to evaluate the effectiveness of breast conservation for newly diagnosed breast cancer. Effectiveness was operationalized as two outcomes within 5 years of the diagnosis of breast cancer: the probability of mastectomy-free survival (either death or mastectomy count as event, whichever comes first), and the probability of mastectomy conditional on survival (mastectomy counts as event, observations censored at death). Methods and Materials: We linked records of 46,687 new cases of breast cancer from 1982 to 1991 in the Ontario Cancer Registry to records of surgery from 1982 to 1995, radiotherapy (RT) from 1982 to 1992, and median household income from the 1986 census. We labeled breast surgery within 4 months and postoperative RT within 12 months of diagnosis as treatment for newly diagnosed breast cancer. Surgery was categorized as mastectomy, lumpectomy plus RT, lumpectomy alone, or no surgical procedure. Among cases that did not undergo mastectomy within 4 months of diagnosis, we labeled mastectomy subsequent to 4 months after diagnosis as treatment failure. We performed life-table analysis and Cox proportional hazards regression, to describe the probability of mastectomy conditional on survival and the probability of mastectomy-free survival. Results: A total of 16,279 cases underwent lumpectomy as the maximum procedure on the breast within 4 months of diagnosis, and 49.7% of these received postoperative RT. Compared to the provincial mean, regions with higher rates of lumpectomy plus RT have higher probability of mastectomy-free survival and lower probability of mastectomy conditional upon survival 5 years after diagnosis of breast cancer. Conclusions: These findings are consistent with a hypothesis that breast conservation is effective in the overall breast cancer population of Ontario within the first 5 years after diagnosis

    The field of oncology is studded with fascinating case reports of rarities, and management of breast cancer by the oncologist has, at times, resulted in the surfacing of such instances of rarities. Pure squamous cell carcinoma (SCC) of the breast is such an example of a rare and generally aggressive malignancy constituting breast cancers. To the best of our knowledge, until 2006, only 5 patients of primary SCC of the breast, which presented clinically as breast abscess, have been reported in medical literature. We report the sixth worldwide case of pure primary SCC of the breast presenting as an abscess. In this report, we highlight the fact that a benign lesion like breast abscess can harbor such a rare malignancy. Clinicians should be aware of that fact, and adequate investigations should be done to rule out that possibility. Extensive literature review has been done to discuss the clinical and radiologic features as well as management of this rare lesion.

    Full Text Available Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Breast involvement by malignant lymphoma, whether primary or secondary, is a rare event. Primary breast lymphomas account for 0.38% - 0.7% of all non-Hodgkin lymphomas, 1.7%-2.2% of all extranodal non-Hodgkin lymphomas, and only 0.04% - 0.5% of all breast cancer cases. Most frequent primary breast lymphomas are diffuse large B cell lymphomas (53%. Breast mucosa-associated lymphoid tissue (MALT lymphomas account for a small fraction of all the MALT lymphomas (1% - 2%. Herein we report a case of a patient with primary breast MALT lymphoma and its presentation on different imaging modalities. Two years after the presentation and treatment with eight cycles of chemotherapy, the patient is alive and well, without evidence of residual disease or recurrence.

    Although conventional mammography is currently the best modality to detect early breast cancer, it is limited in that the recorded image represents the superposition of a three-dimensional (3D) object onto a 2D plane. Recently, two promising approaches for 3D volumetric breast imaging have been proposed, breast tomosynthesis (BT) and CT breast imaging (CTBI). To investigate possible improvements in lesion detection accuracy with either breast tomosynthesis or CT breast imaging as compared to digital mammography (DM), a computer simulation study was conducted using simulated lesions embedded into a structured 3D breast model. The computer simulation realistically modeled x-ray transport through a breast model, as well as the signal and noise propagation through a CsI based flat-panel imager. Polyenergetic x-ray spectra of Mo/Mo 28 kVp for digital mammography, Mo/Rh 28 kVp for BT, and W/Ce 50 kVp for CTBI were modeled. For the CTBI simulation, the intensity of the x-ray spectra for each projection view was determined so as to provide a total average glandular dose of 4 mGy, which is approximately equivalent to that given in conventional two-view screening mammography. The same total dose was modeled for both the DM and BT simulations. Irregular lesions were simulated by using a stochastic growth algorithm providing lesions with an effective diameter of 5 mm. Breast tissue was simulated by generating an ensemble of backgrounds with a power law spectrum, with the composition of 50% fibroglandular and 50% adipose tissue. To evaluate lesion detection accuracy, a receiver operating characteristic (ROC) study was performed with five observers reading an ensemble of images for each case. The average area under the ROC curves (A z ) was 0.76 for DM, 0.93 for BT, and 0.94 for CTBI. Results indicated that for the same dose, a 5 mm lesion embedded in a structured breast phantom was detected by the two volumetric breast imaging systems, BT and CTBI, with statistically

    Breast tumors are the most common cause of cancer in women. The ideal way to detect breast cancer is by a mammography examination. But this test may either be questionable or provide inconclusive data on a significant number of cases, leading to invasive biopsy procedures. The aim of this study is to optimize the detection of breast cancer by gammagraphy to improve the complementary diagnosis provided by a mammography. Consequently and for that reason, a device allowing an optimal patient positioning was designed and built. The materials used for its construction had few gamma radiation absorption properties. The effectiveness of breast gammagraphy was evaluated using by the designed device in two study cases. In both, the definite diagnosis obtained through mammography from doubtful cases was conclusively confirmed. A diagnostic protocol mammogram/gammagraphy was recommended to optimize the selection of patients requiring biopsy. (author)

    A primary mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) of the breast is extremely rare. We report a case of a MALT lymphoma of the breast that presented as a palpable left breast mass in a 37-year-old woman. A physical examination revealed a large firm, and fixed mass in the left inner breast. Mammograms showed a large, isodense mass in the lower inner quadrant of the left breast and an enlarged lymph node in the axilla. A sonogram demonstrated a 5 cm sized, oval, circumscribed, and heterogeneously hypoechoic mass with posterior acoustic enhancement. A surgical biopsy was performed, and the pathology revealed a MALT lymphoma.

    We present a case of chordoma in a patient who had been previously treated for ductal carcinoma of the breast. The initial clinical findings and radiological studies suggested a possibility of metastases. However, the findings also adhered to the classical presentations and findings of the chordoma of the base of skull. It was only after the surgical resection and immunohistochemical confirmation that the diagnosis of chordoma could be established. Here, we discuss chordoma with the analysis of our clinical intrigue.

    Full Text Available Abstract Background Tetrachloroethylene (PCE is an important occupational chemical used in metal degreasing and drycleaning and a prevalent drinking water contaminant. Exposure often occurs with other chemicals but it occurred alone in a pattern that reduced the likelihood of confounding in a unique scenario on Cape Cod, Massachusetts. We previously found a small to moderate increased risk of breast cancer among women with the highest exposures using a simple exposure model. We have taken advantage of technical improvements in publically available software to incorporate a more sophisticated determination of water flow and direction to see if previous results were robust to more accurate exposure assessment. Methods The current analysis used PCE exposure estimates generated with the addition of water distribution modeling software (EPANET 2.0 to test model assumptions, compare exposure distributions to prior methods, and re-examine the risk of breast cancer. In addition, we applied data smoothing to examine nonlinear relationships between breast cancer and exposure. We also compared a set of measured PCE concentrations in water samples collected in 1980 to modeled estimates. Results Thirty-nine percent of individuals considered unexposed in prior epidemiological analyses were considered exposed using the current method, but mostly at low exposure levels. As a result, the exposure distribution was shifted downward resulting in a lower value for the 90th percentile, the definition of "high exposure" in prior analyses. The current analyses confirmed a modest increase in the risk of breast cancer for women with high PCE exposure levels defined by either the 90th percentile (adjusted ORs 1.0-1.5 for 0-19 year latency assumptions or smoothing analysis cut point (adjusted ORs 1.3-2.0 for 0-15 year latency assumptions. Current exposure estimates had a higher correlation with PCE concentrations in water samples (Spearman correlation coefficient = 0.65, p

    PURPOSE: To quantify the risk of second primary breast cancer in the contralateral breast (CB) after radiotherapy (RT) for first breast cancer. METHODS AND MATERIALS: The study population included participants in the Women's Environmental, Cancer, and Radiation Epidemiology study: 708 cases (women...... calculated using multivariable-adjusted conditional logistic regression models. RESULTS: Across all patients, the mean radiation dose to the specific quadrant of the CB tumor was 1.1 Gy. Women 1.0 Gy of absorbed dose to the specific quadrant of the CB had a 2.5-fold greater...... risk for CB cancer than unexposed women (RR = 2.5, 95% CI 1.4-4.5). No excess risk was observed in women >40 years of age. Women 5 years had a RR of 3.0 (95% CI 1.1-8.1), and the dose response was significant (excess RR per Gy of 1.0, 95% CI 0...

    The correct management of genitals and breast cancers and the improving of the preventional and therapeutical successes ratio involve the knowledge of the histopathological features of these nosological entities which have different origins, different risk factors, different simptomatology and also different prognosis. The descriptive evaluation of the histopathological features of the genitals and breast cancers to women from North-Eastern region of Romania. We have been included in the study 96 women (age range 23-77 years, mean 54,49) diagnosed with breast cancer, ovarian cancer, endometrial cancer and cervical cancer at the hospital admission, residency in the Obstetrics and Gynecology Clinics within 23 months. The following main parameters were assessed: histological types, stage at diagnosis, Pap test. After data collection, these have been codified and included in a MS Excel Database, in order to be processed with SPSS 16 and EpiInfo 3.5.1. (2008) Softwares. The following cases' repartition on diagnostic types was observed: breast cancer (44 cases), cervical cancer (24 cases), endometrial cancer (16 cases) and ovarian cancer (12 cases). In our study, the most affected range of age was 40-69 years for breast cancer, 30-59 years for cervical cancer, over 6 years for endometrial cancer and 50-59 years for ovarian cancer. For the cervical neoplasia, 40% of analyzed cases were in incipient stages (in situ to IB stage lessions). More than 50% of breast cancer cases have been diagnosed in advances stages (IIB to IIIC stages). For the endometrium carcinoma, 45% of cases have been identified in incipient stages (in situ to IC). The ovarian neoplasia cases have been detected, most frequently, in advanced stages (III and IV). 25% of women which participated in our study had showed cervical changes. From a histopathological point of view, for cervical neoplasia, squamous carcinoma was the most frequent type (87%), for breast neoplasia--invasive ductal carcinoma (80

    Lymphoepithelioma-like carcinoma (LELC) of the breast is an exceedingly rare variant of mammary cancer. To our knowledge, only twenty - one cases have been reported in the literature. Diagnosis of this type of mammary carcinoma may be challenging, owing to its rarity and the histopathological similarity to common inflammatory and malignant lesions of the breast mainly granulomatous mastitis, medullary carcinoma, pleomorphic lobular carcinoma, lymphoma and other hematological malignancies. Our case is the 22nd case of lymphoepithelioma-like carcinoma reported in the breast, presenting with a palpable tender mass in a post-menopausal female. Her clinical picture had been mistaken for inflammatory disease. We present our case, with its detailed clinical history, radiological findings, histopathological and immune-histochemical findings along with a review of the literature. Highlighting this type of tumors may help in appropriate diagnosis. Moreover, studying the behavior of these rare neoplasms is essential to expedite treatment for this tumor type.

    Full Text Available Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis. Our patient, a 51-year old woman presented with breast lump and history of post-menopausal bleeding. Upon further workup, the patient was diagnosed with cervical cancer. The mammogram and ultrasound of the breast showed multiple lumps within the breast. Histopathology of the breast mass showed metastatic deposit in the breast from cervical cancer. The patient was treated with radiation therapy to the cervix along with concurrent chemotherapy for local control of pain. After completion of local treatment, she started systemic chemotherapy, however she developed health-care associated pneumonia and subdural hematoma leading to deterioration in her performance status. The patient opted for hospice care and died 2 months later. In this report, we will review the presentation of the 38 cases reported in literature and the imaging and histopathologic findings of metastatic deposits to the breast.

    Full Text Available To investigate the relationship between breastfeeding and breast cancer in Southern Brazil, a case-control design was employed, with two age-matched control groups. A total of 250 cases of breast cancer were identified in women from 20 to 60 years of age, with 1,020 hospital and community controls. The main study variables were occurrence of breastfeeding and duration of breastfeeding. A multivariate conditional logistic regression analysis was employed. According to the results, breastfeeding did not have a protective effect against breast cancer. The odds ratio (OR for women who breastfed was 0.9 (95% CI: 0.8-1.2 compared to women who did not breastfeed. For women who breastfed for six months or less, the OR was 1.0 (95% CI: 0.6-1.8. In pre-menopausal women who breastfed for more than 25 months, the OR was 0.95 (95% CI: 0.5-3.5, and in post-menopausal women OR was 1.27 (95% CI: 0.5-3.1, compared to women who had not breastfeed.Para investigar esta relação, entre amamentação e câncer de mama no Sul do Brasil, utilizou-se um delineamento de caso-controle com dois grupos de controles, emparelhados por idade.

    Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants, known human lung carcinogens, and potent mammary carcinogens in laboratory animals. However, the association between PAHs and breast cancer in women is unclear. Vehicular traffic is a major ambient source of PAH exposure. Our study aim was to evaluate the association between residential exposure to vehicular traffic and breast cancer incidence. Residential histories of 1,508 participants with breast cancer (case participants) and 1,556 particpants with no breast cancer (control participants) were assessed in a population-based investigation conducted in 1996-1997. Traffic exposure estimates of benzo[a]pyrene (B[a]P), as a proxy for traffic-related PAHs, for the years 1960-1995 were reconstructed using a model previously shown to generate estimates consistent with measured soil PAHs, PAH-DNA adducts, and CO readings. Associations between vehicular traffic exposure estimates and breast cancer incidence were evaluated using unconditional logistic regression. The odds ratio (95% CI) was modestly elevated by 1.44 (0.78, 2.68) for the association between breast cancer and long-term 1960-1990 vehicular traffic estimates in the top 5%, compared with below the median. The association with recent 1995 traffic exposure was elevated by 1.14 (0.80, 1.64) for the top 5%, compared with below the median, which was stronger among women with low fruit/vegetable intake [1.46 (0.89, 2.40)], but not among those with high fruit/vegetable intake [0.92 (0.53, 1.60)]. Among the subset of women with information regarding traffic exposure and tumor hormone receptor subtype, the traffic-breast cancer association was higher for those with estrogen/progesterone-negative tumors [1.67 (0.91, 3.05) relative to control participants], but lower among all other tumor subtypes [0.80 (0.50, 1.27) compared with control participants]. In our population-based study, we observed positive associations between vehicular traffic

    Supernumerary breast or polymastia is a well documented anomaly of the breast, and commonly presents along the embryonic milk line extending between the axilla and groin. However, cases of polymastia have been recorded in the face, vulva, and perineum. The clinical significance of these anomalies include their susceptibility to inflammatory and malignant changes, and their association with other congenital anomalies of the urinary and cardiovascular systems. In this article we report a case of fibroadenoma that developed in the supernumerary breast of the right axilla in a 17-year-old girl. It is uncommon to find such palpable masses in young patients. Clinical and sonographic examination of both breasts revealed no abnormalities and no lymph nodes were detected in the axillae or the neck. No associated urologic or cardiovascular abnormalities were found, and the histopathological examination of the excisional biopsy samples showed a well-defined, capsulated intracanalicular type of fibroadenoma similar to that of eutopic mammary tissue. In this report, we describe a rare case of fibroadenoma in an accessory breast in a young woman. There are a fewer than 40 reports in the world about this subject, of which differential diagnoses include: cancer in axillary supernumerary breast, hidradenitis, axillary lymphadenomegaly, lipomas, anexial cutaneous neoplasia, cysts, and phylloides tumor. The combination of clinical examination, ultrasound, and cytology leads to adequate treatment, especially surgical. The diagnosis could be confused because of findings from cytology. In this case, because of the clinical and sonographic findings and multiple differential diagnosis, only the histopathological study was used to confirm the diagnosis. Despite its high sensitivity, cytology has low specificity and could create false positive results. However, atypical lesions can be seen in fibroadenomas, especially in younger patients, pregnant patients, and in patients who use hormonal

    The position of the patient together with the configuration of the treatment fields play an important role in the volume of lung irradiated in breast techniques. These factors are even more important when the staging of the disease is advanced. A comparison of lung volumes is made with the patient in three treatment positions, and the effect of beam angling is demonstrated. A method of calculating the approximated lung volume from port films is proposed, together with a comparative analysis of the data obtained. Clinical decisions affecting technical considerations are examined. 6 refs., 5 figs

    Post-radiation malignant fibrous histiocytoma (MFH) of the breast is extremely rare. We report a case of post-radiation MFH that presented a rapidly growing mass in a 52-year-old woman who underwent breast-conserving therapy and adjuvant whole breast irradiation 6 years ago. To the best of our knowledge, only one case of primary MFH of the female breast have been reported with sonographic findings. We analyzed the sonographic and MRI findings with correlative histopathologic features, and then confirmed with surgical excision.

    Purpose: To quantify the risk of second primary breast cancer in the contralateral breast (CB) after radiotherapy (RT) for first breast cancer. Methods and Materials: The study population included participants in the Women's Environmental, Cancer, and Radiation Epidemiology study: 708 cases (women with asynchronous bilateral breast cancer) and 1399 controls (women with unilateral breast cancer) counter-matched on radiation treatment. Participants were 1.0 Gy of absorbed dose to the specific quadrant of the CB had a 2.5-fold greater risk for CB cancer than unexposed women (RR = 2.5, 95% CI 1.4-4.5). No excess risk was observed in women >40 years of age. Women 5 years had a RR of 3.0 (95% CI 1.1-8.1), and the dose response was significant (excess RR per Gy of 1.0, 95% CI 0.1-3.0). Conclusions: Women 1.0 Gy to the CB had an elevated, long-term risk of developing a second primary CB cancer. The risk is inversely related to age at exposure and is dose dependent

    Young women presenting with breast cancer are more likely to have a genetic predisposition to the disease than breast cancer patients in general. A genetic predisposition is known to increase the risk of new primary breast (and other) cancers. It is unclear from the literature whether genetic status should be taken into consideration when planning adjuvant treatment in a young woman presenting with a first primary breast cancer. The primary aim of the POSH study is to establish whether genetic status influences the prognosis of primary breast cancer independently of known prognostic factors. The study is a prospective cohort study recruiting 3,000 women aged 40 years or younger at breast cancer diagnosis; the recruiting period covers 1 st June 2001 to 31 st December 2007. Written informed consent is obtained at study entry. Family history and known epidemiological risk data are collected by questionnaire. Clinical information about diagnosis, treatment and clinical course is collected and blood is stored. Follow up data are collected annually after the first year. An additional recruitment category includes women aged 41 to 50 years who are found to be BRCA1 or BRCA2 gene carriers and were diagnosed with their first breast cancer during the study recruiting period. Power estimates were based on 10% of the cohort carrying a BRCA1 gene mutation. Preliminary BRCA1 and BRCA2 mutation analysis in a pilot set of study participants confirms we should have 97% power to detect a difference of 10% in event rates between gene carriers and sporadic young onset cases. Most of the recruited patients (>80%) receive an anthracycline containing adjuvant chemotherapy regimen making planned analyses more straightforward

    Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.

    This pilot study was undertaken to investigate the significance of some tumour angiogenic factors (e.g. MMP, ADAM-12 and VEGF) and tumour angiogenic inhibitors (endostatin and TIMP-1) in the aetiology of breast cancer and their responsiveness to cancer treatment as well . We also sought to assess the significance of these angiogenic and antiangiogenic factors in the prognosis and diagnosis of breast cancer. The cases were allocated into five groups: Normal control group (Gr.l), fibroadenoma (Gr.l l), breast cancer (invasive duct carcinoma type grade l l) (Gr.lll) , breast cancer + chemo hormonal therapy (Gr.IV), and breast cancer + chemo hormonal and radiotherapy (Gr.V).Results obtained from this study reported absence of matrix metalloproteinase-9 (MMP-9)activity in the urine and serum of normal subjects and fibroadenoma patients and its significant depression in the urine and serum of breast cancer patients treated with chemo hormonal therapy alone or followed by radiotherapy, compared to breast cancer group as reference. A significantly mild elevation in urinary MMP-2 activity and a non significant change in its activity in the serum of fibroadenoma patients, compared to the dramatic rise in the urine and serum of breast cancer patients were observed

    The history of the radiological examination of the breast has been long, and recently the methods for examining the breast are variable: mammography, thermography, xeroradiography, ultrasonography, water-path sonography, transillumination, mammary C.T., M.R imaging, infra-red scanning, nuclear medicine, and galactography. Most of these methods were not proven or have not been satisfied on their clinical testing but conventional mammography has been the gold standard for diagnosis of the breast cancer and no other method has reached its effectiveness. The authors performed mammography in 488 patients with breast abnormalities who had visited to Yeung Nam University hospital from May, 1983 to December, 1984. And we analyzed the mammographic findings and diagnostic accuracy in pathologically confirmed 53 cases by operations or biopsies. The results are as follows: 1. Among 16 cases of breast malignancies (1) the most prevalent age group is 6th decade (37.5%), followed by 5th decade (31.3%), (2) the most common pathologic type is ductal carcinoma (93.75%), (3) the masses are larger than 2cm in 8 cases, smaller than 2cm in 5 cases, and no visible mass is observed in 3 cases. 2. Among 37 cases of benign breast diseases, (1) the most prevalent age group is 4th and 5th decades (each 11 cases), and followed by 3rd decade (8 cases), (2) the most common disease is benign tumor (17 cases), followed by fibrocystic dysplasia (13 cases), and inflammating disease (7 cases), (3) radiologically visible masses are observed in 16 cases and the masses are smaller than 2cm in 11 cases. 3. The diagnostic accuracy of mammography compared with that of pathology, (1) in malignancy, the accuracy rate is 75% (12/16 cases), and 87% (32/37 cases) in benign diseases, (2) average accuracy rate is 81% (44/53 cases)

    Full Text Available Abstract Metastases to the breast are unusual lesions that make up approximately 2% of all malignant mammary neoplasms and may mimic both benign and malignant primary neoplasms from a clinical point of view, as well as in imaging studies. Arriving at a correct diagnosis is therefore essential in order to establish appropriate management. We present three cases of metastatic neoplasms diagnosed through fine needle aspiration biopsy and immunocytochemistry. The cytological diagnoses were: medulloblastoma in an 18-year-old woman, melanoma in a 26-year-old man, and an exceptional case of ovarian sarcoma originating from a granulosa cell tumor with metastases to both breasts. A metastatic disease should be considered in the differential diagnosis of a palpable mass in the breast, especially if there is a history of an extramammary malignant neoplasm. Fine needle aspiration biopsy is the method of choice for the management of these cases. Whenever possible the exam of the material obtained should be compared to the previous biopsy, which is usually enough to arrive at a correct diagnosis, thus preventing unnecessary surgical procedures.

    The ataxia telangiectasia mutated (ATM) gene is a tumor suppressor gene with functions in cell cycle arrest, apoptosis, and repair of DNA double-strand breaks. Based on family studies, women heterozygous for mutations in the ATM gene are reported to have a fourfold to fivefold increased risk of breast cancer compared with noncarriers of the mutations, although not all studies have confirmed this association. Haplotype analysis has been suggested as an efficient method for investigating the role of common variation in the ATM gene and breast cancer. Five biallelic haplotype tagging single nucleotide polymorphisms are estimated to capture 99% of the haplotype diversity in Caucasian populations. We conducted a nested case–control study of breast cancer within the Nurses' Health Study cohort to address the role of common ATM haplotypes and breast cancer. Cases and controls were genotyped for five haplotype tagging single nucleotide polymorphisms. Haplotypes were predicted for 1309 cases and 1761 controls for which genotype information was available. Six unique haplotypes were predicted in this study, five of which occur at a frequency of 5% or greater. The overall distribution of haplotypes was not significantly different between cases and controls (χ 2 = 3.43, five degrees of freedom, P = 0.63). There was no evidence that common haplotypes of ATM are associated with breast cancer risk. Extensive single nucleotide polymorphism detection using the entire genomic sequence of ATM will be necessary to rule out less common variation in ATM and sporadic breast cancer risk

    Full Text Available Background: Breast Cancer is the most frequent neoplasm causing death in women between 35-55 years of age. Of the Prognostic indicators existing for breast cancer, axillary lymph node status has been regarded as the most important one. Twenty to thirty percent of all lymph node negative patients will still develop a recurrence of the disease within 10 years of initial treatment. Therefore, a new prognostic marker that could identify patients at high risk of tumor recurrence more accurately than existing indicators would be of great value, one potential indicator is tumor-induced angiogenesis. Materials and Methods: This is a six months prospective (January 2010-June 2010 and 1 year retrospective (Jan2009-Dec2009 study which included thirty five breast cancer cases visiting the Surgical OPD. Angiogenesis was estimated by determining micro vessel counting after immune staining the paraffin embedded tissue sections using anti-CD34 antibody. Results: Age of the patients ranged from 25 to 80 years with a mean age of 45.48 years. Most of the cases were infiltrating ductal carcinoma comprising of 33 cases (94.28%. Three cases (9.10% showed vascular invasion by the tumor. Majority showed (63.64% vessel count of less than 200 per 10 high power fields. Conclusion: Micro vascular density positively correlated with size of the tumor, lymph nodes involved by the tumor and Nottingham prognostic index. In the future, Antibodies specific to proliferating endothelium, together with the development of automated image analysis, may improve the accuracy and value of measuring angiogenesis-induced microvessel density.

    Breast metastasis from extra-mammary malignancy is rare. An incidence of 0.4% to 1.3% has been reported in literature. hTe primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. In this report, two cases of pulmonary metastasis to the breast were presented. A 40-year-old female manifested a right breast mass of 2-month duration. Atfer physical examination was performed, a poorly deifned mass was noted in the upper outer quadrant of the right breast. Another 49-year-old female manifested right breast mass of 5-day duration. A poorly deifned mass was noted in the lower inner quadrant of the right breast. Mammography results also revealed breast cancer. hTe patients underwent local excision. Atfer histological and immunohistochemical analyses were conducted, a primary lung carcinoma that metastasized to the breast was diagnosed. An accurate differentiation of metastasis to the breast from primary breast cancer is very important because the treatment and prognosis of the two differ signiifcantly.

    Paget breast disease is a kind of intraductal carcinoma that through an intracanalicular diffusion invades the basal epidermal layer, reaching the areola and nipple, producing a typical erythematous desquamative eczematous-like lesion. This neoplasia can remain undetected for a long time and inadequately treated as a dermatological affection. Synchronous or metachronous lesions are very uncommon. Surgical choice is conditioned by the presence of a tumor below the epidermal lesion, by its dimensions, and by the possible lymph node involvement. Surgical therapy can be radical or conservative. From our experience we think that lesion biopsy is always necessary to formulate a correct diagnosis and to schedule an appropriate therapeutic approach. In our case, a biopsy was performed first, then on the basis of the frozen section analysis a radical mastectomy with axillary third level lymph nodes dissection, because of the large dimensions of the lesion and the previous history of a methachronous lesion.

    It is expected that, by 2020, 15 million new cases of cancer will occur every year in the world, one million of them in Africa. Knowledge of cancer trends in African countries is far from adequate, and improvements in cancer prevention efforts are urgently needed. The aim of this study was to characterize breast cancer clinically and pathologically at presentation in Luanda, Angola; we additionally provide quality information that will be useful for breast cancer care planning in the country. Data on breast cancer cases were retrieved from the Angolan Institute of Cancer Control, from 2006 to 2014. For women diagnosed in 2009 (5-years of follow-up), demographic, clinical and pathological information, at presentation, was collected, namely age at diagnosis, parity, methods used for pathological diagnoses, tumor pathological characteristics, stage of disease and treatment. Descriptive statistics were performed. The median age of women diagnosed with breast cancer in 2009 was 47 years old (range 25-89). The most frequent clinical presentation was breast swelling with axillary lymph nodes metastasis (44.9 %), followed by a mass larger than 5 cm (14.2 %) and lump (12.9 %). Invasive ductal carcinoma was the main histologic type (81.8 %). Only 10.1 % of cancer cases had a well differentiated histological grade. Cancers were diagnosed mostly at advanced stages (66.7 % in stage III and 11.1 % in stage IV). In this study, breast cancer was diagnosed at a very advanced stage. Although it reports data from a single cancer center in Luanda, Angola it reinforces the need for early diagnosis and increasing awareness. According to the main challenges related to breast cancer diagnosis and treatment herein presented, we propose a realistic framework that would allow for the implementation of a breast cancer care program, built under a strong network based on cooperation, teaching, audit, good practices and the organization of health services. Angola needs urgently a program for

    Fibromyalgia syndrome after comprehensive treatment of breast cancer is rare and seldom reported. Here we present a case of a 50-year-old female patient,who was admitted to the hospital because of generalized fibromyalgia for 3 months and brain metastasis after the right breast carcinoma surgery for 1 month, and the clinical diagnosis was brain metastasis from breast carcinoma combined with fibromyalgia syndrome. The fibromyalgia were relieved with proper symptomatic treatment but the patient eventually died of tumor progression.

    A case of breast cancer that metastasized to the head of the pancreas 6 yearsand 8 months after mastectomy is reported. The pancreas head metastasis was associated with general fatigue and obstructive jaundice. The serum levels of CEA, CA15-3 and NCC-ST-439, tumor markers of breast cancer, were within normal limits, but CA15-3 was immunohistochemically demonstrated in the resected metastatic lesion, in a manner similar to lobular carcinoma of the breast.

    We report the outcomes of the European prospective study on prepectoral breast reconstruction using preshaped acellular dermal matrix for complete breast implant coverage. Seventy-nine patients were enrolled between April 2014 and August 2015 all over Europe using a single protocol for patient selection and surgical procedure, according to the Association of Breast Surgery and British Association of Plastic Reconstructive and Aesthetic Surgeons joint guidelines for the use of acellular dermal matrix in breast surgery. The preshaped matrix completely wraps the breast implant, which is placed above the pectoralis major, without detaching the muscle. A total of 100 prepectoral breast reconstructions with complete implant coverage were performed. This series, with mean follow-up of 17.9 months, had two cases of implant loss (2.0%) including one necrosis of the nipple and one wound breakdown (1.0% respectively). No implant rotations were observed. Good cosmetic outcomes were obtained with natural movement of the breasts and softness to the touch; none of the patients reported experiencing pain or reduction in the movements of the pectoralis major muscle postoperatively. The use of preshaped acellular dermal matrix for a complete breast implant coverage in selected patients is safe and gives satisfactory results, both from the aesthetic view point and the low postoperative complication rates. Further studies reporting long-term outcomes are planned. © 2017 Crown copyright. The Breast Journal © 2017 Wiley Periodicals, Inc.

    This study evaluated the role of breast magnetic resonance (MR) imaging in the selective study breast implant integrity. We retrospectively analysed the signs of breast implant rupture observed at breast MR examinations of 157 implants and determined the sensitivity and specificity of the technique in diagnosing implant rupture by comparing MR data with findings at surgical explantation. The linguine and the salad-oil signs were statistically the most significant signs for diagnosing intracapsular rupture; the presence of siliconomas/seromas outside the capsule and/or in the axillary lymph nodes calls for immediate explantation. In agreement with previous reports, we found a close correlation between imaging signs and findings at explantation. Breast MR imaging can be considered the gold standard in the study of breast implants.

    Introduction: Tryptophan oxidation via the kynurenine pathway is an important mechanism of tumoral immunoresistance. Increased tryptophan metabolism via the serotonin pathway has been linked to malignant progression in breast cancer. In this study, we combined quantitative positron emission tomography (PET) with tumor immunohistochemistry to analyze tryptophan transport and metabolism in breast cancer. Methods: Dynamic α-[ 11 C]methyl-L-tryptophan (AMT) PET was performed in nine women with stage II–IV breast cancer. PET tracer kinetic modeling was performed in all tumors. Expression of L-type amino acid transporter 1 (LAT1), indoleamine 2,3-dioxygenase (IDO; the initial and rate-limiting enzyme of the kynurenine pathway) and tryptophan hydroxylase 1 (TPH1; the initial enzyme of the serotonin pathway) was assessed by immunostaining of resected tumor specimens. Results: Tumor AMT uptake peaked at 5–20 min postinjection in seven tumors; the other two cases showed protracted tracer accumulation. Tumor standardized uptake values (SUVs) varied widely (2.6–9.8) and showed a strong positive correlation with volume of distribution values derived from kinetic analysis (P < .01). Invasive ductal carcinomas (n = 6) showed particularly high AMT SUVs (range, 4.7–9.8). Moderate to strong immunostaining for LAT1, IDO and TPH1 was detected in most tumor cells. Conclusions: Breast cancers show differential tryptophan kinetics on dynamic PET. SUVs measured 5–20 min postinjection reflect reasonably the tracer's volume of distribution. Further studies are warranted to determine if in vivo AMT accumulation in these tumors is related to tryptophan metabolism via the kynurenine and serotonin pathways.

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

    Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual studies and resulting low statistical power to subcategorize exposures or to study specific subtypes. The Premenopausal Breast Cancer Collaborative Group was established to facilitate cohort-based analyses of risk factors for premenopausal breast cancer by pooling individual-level data from studies participating in the United States National Cancer Institute Cohort Consortium. This paper describes the Group, including the rationale for its initial aims related to pregnancy, obesity, and physical activity. We also describe the 20 cohort studies with data submitted to the Group by June 2016. The infrastructure developed for this work can be leveraged to support additional investigations. PMID:28600297

    breast feeding has a number of well-documented benefits. Numerous studies have been conducted to investigate an effective approach to increase the breast feeding rate, duration and exclusive breast feeding rate, in which maternal breast feeding self-efficacy was determined as one of the major contributors. Although numerous breast feeding educational programmes have been developed to enhance maternal breastfeeding self-efficacy, results on the effectiveness of these programmes remain inconclusive. this study aims to investigate the effectiveness of a self-efficacy-based breast feeding educational programme (SEBEP) in enhancing breast feeding self-efficacy, breast feeding duration and exclusive breast feeding rates among mothers in Hong Kong. eligible pregnant women were randomized to attend a 2.5-hour breast feeding workshop at 28-38 weeks of gestation and receive 30-60minutes of telephone counselling at two weeks post partum, whereas both intervention and control groups received usual care. At two weeks postpartum, the Breast feeding Self-Efficacy Scale-Short Form (BSES-SF) and a self-developed post partum questionnaire were completed via telephone interviews. The breast feeding duration, pattern of breast feeding and exclusive breast feeding rates were recorded at two weeks, four weeks, eight weeks and six months post partum. results of analyses based on an intention-to-treat (ITT) assumption showed a significant difference (p<0.01) in the change in BSES-SF mean scores between the mothers who received SEBEP and those who did not receive SEBEP at two weeks post partum. The exclusive breast feeding rate was 11.4% for the intervention group and 5.6% for the control group at six months post partum. the findings of this study highlight the feasibility of a major trial to implement breast feeding education targeted at increasing breast feeding self-efficacy and exclusive breast feeding rates in Hong Kong.

    Pregnancy-associated breast cancer is defined as breast cancer diagnosed during pregnancy and up to one year postpartum. A retrospective, analytical, observational study comparing 56 cases of breast cancer and pregnancy (PABC) diagnosed 1976-2008 with 73 patients with breast cancer not associated with pregnancy (non-PABC) was performed. Demographic data, prognostic factors, treatment and survival were reviewed and compared. The prevalence of PABC in our center is 8.3/10,000. The highest frequency (62%) appeared during the postpartum period. The stages are higher in PABC, being 31.3% advanced (EIII and EIV) in PABC versus 13.3% in non-PABC (P < .05). Regarding prognostic factors, 27.3% in PABC had a tumoral grade 3 versus 15.8% of non-PABC. Among women with PABC, 33.3% had negative estrogen receptors, 48.7% negative progesterone receptors and 34.5% positive Her2Neu compared with 22.2, 24.1 and 31%, respectively of non-PABC patients. Finally, positive lymph nodes were found in 52.8% of PABC, versus 33.8% non-PABC (P < .05). Overall and disease-free survival rate at 5 years for PABC was 63.7 and 74.2%, respectively. The poorer survival observed is possibly due to the presence of adverse prognostic features such as lymph node metastases, negative hormone receptors, tumoral grade iii, as well as a delay in diagnosis with a higher rate of advanced stages.

    Primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. There are not many cases reported in the English literature since it was first documented in 1983. Reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. Herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, masquerading as an inflammatory breast condition in a 22-year-old young lady, perhaps the youngest case ever reported in the English literature. We discuss the imaging features and highlight the Doppler ultrasonographic findings of this rare breast carcinoma.

    To study the clinical and pathologic features of granulomatous lobular mastitis (GLM). Sixty-eight cases of GLM were retrieved from the archival file. The clinical data and histologic features were retrospectively reviewed. Sixty-eight patients presented with breast mass. Ulceration in overlying breast skin was seen in 9 cases. Most of the patients had history of breast feeding. None of them had evidence of specific infections involving the breast. The clinical and radiologic features mimicked malignancy. Histologically, GLM was characterized by the presence of non-necrotizing granulomas, usually admixed with neutrophils and associated with benign ductolobular units. The ductolobular architecture was still preserved. The duration of follow up ranged from 6 to 36 months. Four patients suffered from disease recurrence. GLM shows clinical and radiologic features reminiscent of breast cancer. Correct diagnosis requires histologic examination of the biopsy specimens.

    Purpose: To validate and compare the accuracy of breast tissue segmentation methods applied to computed tomography (CT) scans used for radiation therapy planning and to study the effect of tissue distribution on the segmentation accuracy for the purpose of developing models for use in adaptive breast radiation therapy. Methods and Materials: Twenty-four patients receiving postlumpectomy radiation therapy for breast cancer underwent CT imaging in prone and supine positions. The whole-breast clinical target volume was outlined. Clinical target volumes were segmented into fibroglandular and fatty tissue using the following algorithms: physical density thresholding; interactive thresholding; fuzzy c-means with 3 classes (FCM3) and 4 classes (FCM4); and k-means. The segmentation algorithms were evaluated in 2 stages: first, an approach based on the assumption that the breast composition should be the same in both prone and supine position; and second, comparison of segmentation with tissue outlines from 3 experts using the Dice similarity coefficient (DSC). Breast datasets were grouped into nonsparse and sparse fibroglandular tissue distributions according to expert assessment and used to assess the accuracy of the segmentation methods and the agreement between experts. Results: Prone and supine breast composition analysis showed differences between the methods. Validation against expert outlines found significant differences (P<.001) between FCM3 and FCM4. Fuzzy c-means with 3 classes generated segmentation results (mean DSC = 0.70) closest to the experts' outlines. There was good agreement (mean DSC = 0.85) among experts for breast tissue outlining. Segmentation accuracy and expert agreement was significantly higher (P<.005) in the nonsparse group than in the sparse group. Conclusions: The FCM3 gave the most accurate segmentation of breast tissues on CT data and could therefore be used in adaptive radiation therapy-based on tissue modeling. Breast tissue segmentation

    Mammographic breast density is a known breast cancer risk factor. Studies have shown the potential to automate breast density estimation by using computerized texture-based segmentation of the dense tissue in mammograms. Digital breast tomosynthesis (DBT) is a tomographic x-ray breast imaging modality that could allow volumetric breast density estimation. We evaluated the feasibility of distinguishing between dense and fatty breast regions in DBT using computer-extracted texture features. Our long-term hypothesis is that DBT texture analysis can be used to develop 3D dense tissue segmentation algorithms for estimating volumetric breast density. DBT images from 40 women were analyzed. The dense tissue area was delineated within each central source projection (CSP) image using a thresholding technique (Cumulus, Univ. Toronto). Two (2.5cm)2 ROIs were manually selected: one within the dense tissue region and another within the fatty region. Corresponding (2.5cm)3 ROIs were placed within the reconstructed DBT images. Texture features, previously used for mammographic dense tissue segmentation, were computed. Receiver operating characteristic (ROC) curve analysis was performed to evaluate feature classification performance. Different texture features appeared to perform best in the 3D reconstructed DBT compared to the 2D CSP images. Fractal dimension was superior in DBT (AUC=0.90), while contrast was best in CSP images (AUC=0.92). We attribute these differences to the effects of tissue superimposition in CSP and the volumetric visualization of the breast tissue in DBT. Our results suggest that novel approaches, different than those conventionally used in projection mammography, need to be investigated in order to develop DBT dense tissue segmentation algorithms for estimating volumetric breast density.

    Fibromatosis of the breast, also known as a desmoid tumor, is extremely rare and most often appears as an aggressive lesion mimicking breast carcinoma. It lacks metastatic potential but can grow aggressively in a localized area. Ultrasonography often shows an irregular spiculated hypoechoic mass with posterior acoustic shadowing. We discuss a case of breast fibromatosis that presented as a painful palpable breast mass in a 32-year-old woman and mimicked an abscess in the sonogram. We found that this lesion displayed atypical sonographic features such as a heterogeneous echoic mass with an internal anechoic area. Copyright © 2015 Elsevier Inc. All rights reserved.

    Granular cell tumors (GCT) of the breast are uncommon benign neoplasms that are usually indistinguishable from breast cancer with respect to their clinical and radiological presentation. FNAB can be a usefull diagnostic tool, but histological examination is essential for the correct diagnosis. This benign tumor should be considered among the diagnostic possibilities in the presence of a lesion with mammographic and ultrasonographic indications of highly probable malignancy. We present three cases of breast GCT that mimicked primary breast cancer. Benign neoplasm was diagnosed and local excision was carried out rather than mastectomy and lymphadenectomy. (Author) 9 refs

    As, quest for beauty has always been an aim. There is a need to define the "ideal" beautifull breast with objective caracteristics, usable in plastic, reconstructive and aesthetic surgery. After, we have defined the necessary parameters usable in breast surgery. We realized an anthropomorphic study including 70 volunteer women and one molded model. Multiple pictures have been taken for each volunteer, that were evaluated and noted by five plastic surgeon, five doctors from other speciality, five women, five men. A twenty notation was used for this study. The main values for the ten women that obtained best notation (>or=14/20) were used in order to defined the ideal measures for surgery. Breast arrow and breast arrow over the trunck height were the most significant factors. According statistical studies, this fraction is about 0,387 (P=0,000969). The nice breast has a round shape and look like juvenile breast. Bra size, cup size, base, segments II and III, fraction II/III are not significant in our series of (non operated) natural breast. The ideal breast is in harmony and proportional to the trunck height, with the main fraction of breast arrow on the trunck height about 0,387 in our serie.

    Full Text Available Background: Cancer has become one of the ten leading causes of death in India. Breast cancer is the most common diagnosed malignancy in India, it ranks second to cervical cancer. An increasing trend in incidence is reported from various registries of national cancer registry project and now India is a country with largest estimated number of breast cancer deaths worldwide. Aim: To study the factors associated with breast cancer. Objectives: To study the association between breast cancer and selected exposure variables and to identify risk factors for breast cancer. Materials and Methods: A hospital based Case control study was conducted at Shirdi Sai Baba Cancer Hospital and Research Center, Manipal, Udupi District. Results: Total 188 participants were included in the study, 94 cases and 94 controls. All the study participants were between 25 to 69 years of age group. The cases and controls were matched by ± 2 years age range. Non vegetarian diet was one of the important risk factors (OR 2.80, CI 1.15-6.81. More than 7 to 12 years of education (OR 4.84 CI 1.51-15.46 had 4.84 times risk of breast cancer as compared with illiterate women. Conclusion: The study suggests that non vegetarian diet is the important risk factor for Breast Cancer and the risk of Breast Cancer is more in educated women as compared with the illiterate women. Limitation: This is a Hospital based study so generalisability of the findings could be limited.

    Pre-clinical studies support an anti-cancer effect of statin drugs, yet epidemiological evidence remains inconsistent regarding their role in breast cancer primary prevention. Here we report an updated analysis of the association between statin use and breast cancer incidence in the Nurses’ Health Study cohort. Post-menopausal Nurses’ Health Study participants without a cancer history were followed from 2000 until 2012 (n=79,518). Data on statin use were retrieved from biennial questionnaires. We fit Cox regression models to estimate associations between longitudinal statin use and breast cancer incidence. Over 823,086 person-years of follow-up, 3,055 cases of invasive breast cancer occurred. Compared with never users, both former and current statin users had similar rates of invasive breast cancer incidence (former users: HRadj=0.96, 95% CI: 0.82, 1.1; current users: HRadj=1.1, 95% CI: 0.92, 1.3). Associations did not differ by estrogen receptor status or histology (ductal vs. lobular carcinoma). Statin use was not associated with risk of invasive breast cancer, irrespective of histological subtype and ER status. Statin drugs do not appear to modify processes involved in breast cancer initiation. PMID:26762806

    The physiology of the nonlactating human breast likely plays a key role in factors that contribute to the etiology of breast cancer and other breast conditions. Although there has been extensive research into the physiology of lactation, few reports explore the physiology of the resting mammary gland, including mechanisms by which compounds such as hormones, drugs, and potential carcinogens enter the breast ducts. The purpose of this study was to explore transport of exogenous drugs into ductal fluid in nonlactating women and determine if their concentrations in the fluid are similar to those observed in the breast milk of lactating women. We selected two compounds that have been well characterized during lactation, caffeine and cimetidine. Caffeine passively diffuses into breast milk, but cimetidine is actively transported and concentrated in breast milk. After ingestion of caffeine and cimetidine, 14 nonlactating subjects had blood drawn and underwent ductal lavage at five time points over 12 h to measure drug levels in the fluid and blood. The concentrations of both caffeine and cimetidine in lavage fluid were substantially less than those observed in breast milk. Our results support recent evidence that the cimetidine transporter is not expressed in the nonlactating mammary gland, and highlight intriguing differences in the physiology and molecular transport of the lactating and nonlactating breast. The findings of this exploratory study warrant further exploration into the physiology of the nonlactating mammary gland to elucidate factors involved in disease initiation and progression.

    Full Text Available BACKGROUND: Developing countries with traditionally breastfeeding are now experiencing the increasing pressure of formula milk marketing. This may endanger lives and undermine the efforts of national policies in achieving the objectives of the Millennium Development Goals. We examined the use of, and factors for use, of all available breast-milk substitutes (BMS in a country with a traditionally high rate of breastfeeding. METHODS: Randomised multi-stage sampling surveys in 90 villages in 12/17 provinces in Laos. PARTICIPANTS: 1057 mothers with infants under 24 months of age. TOOLS: 50-query questionnaire and a poster of 22 BMS (8 canned or powdered milk; 6 non-dairy; 6 formulas; 2 non-formulas. OUTCOME MEASURES INCLUDED: prevalence of use and age of starting BMS in relation to socio-demographic characteristics and information sources, by univariate and multivariate analyses. RESULTS: Of 1057 mothers: 72.5% currently breastfed; 25.4% gave BMS (10.6% infant formula; 19.6% gave BMS before 6 months of age (of them: 83% non-dairy or cereals; mean age: 2.9 months; 95% Confidence interval: 2.6-3.2. One formula and one non-formula product accounted for 85% of BMS. BMS were considered as milk by the majority of mothers. Thai TV was the main source of information on BMS for mothers. Lao Loum mothers (the main ethnic group living in concrete houses with good sanitary conditions, were more likely than others to use BMS before 6 months (OR: 1.79, (1.15-2.78, p<0.009. Mothers who fed their infants colostrum at birth were less likely to use BMS before 6 months of age (OR: 0.63, (0.41-0.99, p = 0.04. Unemployed mothers living in rural areas were less likely to consider BMS better than breast milk. CONCLUSION: In Laos, mothers with the highest socio-economic status are showing a tendency to give up breastfeeding. Successful educational strategies and advocacy measures should be urgently developed to promote and sustain breastfeeding in developing countries.

    Breastfeeding has a major impact on CMV epidemiology. Postnatal CMV reactivation's incidence during lactation is nearby the maternal seroprevalence. Although perinatal CMV infection has practically no consequences in term newborn, it may cause, in some cases, a severe symptomatic disease in preterm newborns. The aims of the present study are to evaluate the rate and clinical expression of CMV infection breast milk transmitted in preterm infants and to check the safety of the freezing treated breast milk. The study included fifty-seven preterm infants and their CMV seropositive mothers. Fresh breast milk samples have been collected from 1(st) to 9(th) postpartum week. Both fresh breast milk and 72, 96, 120 hours frozen samples have been examined, checking the presence of CMV; urine samples have been tested too. 70.2% of tested mothers showed reactivation of the infection, and CMV-positive breast milk during the six weeks postpartum has been found. However, only one infant was infected by CMV, developing hepatic affection concomitantly with a multi-system involvement, as shown CMV DNA detection in urine, saliva, blood, gastric aspirate, and stools. Freezing breast milk at -20°C and pasteurization may respectively reduce or eliminate the viral load.

    Breast cancer is still considered as the most common form of cancer as well as the leading causes of cancer deaths among women all over the world. We aim to provide a web-based breast ultrasound database for online training inexperienced radiologists and giving computer-assisted diagnostic information for detection and classification of the breast tumor. We introduce a web database which stores breast ultrasound images from breast cancer patients as well as their diagnostic information. A web-based training system using a feature scoring scheme based on Breast Imaging Reporting and Data System (BI-RADS) US lexicon was designed. A computer-aided diagnosis (CAD) subsystem was developed to assist the radiologists to make scores on the BI-RADS features for an input case. The training system possesses 1669 scored cases, where 412 cases are benign and 1257 cases are malignant. It was tested by 31 users including 12 interns, 11 junior radiologists, and 8 experienced senior radiologists. This online training system automatically creates case-based exercises to train and guide the newly employed or resident radiologists for the diagnosis of breast cancer using breast ultrasound images based on the BI-RADS. After the trainings, the interns and junior radiologists show significant improvement in the diagnosis of the breast tumor with ultrasound imaging (p-value  .05). The online training system can improve the capabilities of early-career radiologists in distinguishing between the benign and malignant lesions and reduce the misdiagnosis of breast cancer in a quick, convenient and effective manner.

    Full Text Available BACKGROUND Despite the fact that in majority of cases the initial symptom of benign breast disease is a lump, which can be easily detected by the patient herself by self-examination they generally present at a very late stage and this poses a great difficulty in their management. Early and appropriate diagnosis of breast disease is of utmost importance. AIM The aim of the study was to find out the relative frequency and commonest site of occurrence of benign breast disorder and their relationship with age, parity, menstrual cycle, and socio-economic status and also to find out the accuracy of investigative procedures in their diagnosis. DESIGN This is a cross sectional, interventional. Hospital based study. MATERIALS AND METHOD This study was done in 58 female patients in the age group 10 yrs. to 55 yrs. presenting with clinically benign
